About The Book

Gemini is an unforgettable novel—a morality tale, a mystery, and a love story that will leave readers breathless” (Maria Semple, New York Times bestselling author of Where’d You Go, Bernadette).

As should be the case with any memorable love story, the first time Raney Remington saw Bo she hated him.

When the skinny kid from the city first arrives in her Pacific Northwest hometown, Raney doesn’t quite know what to make of him. Yet her intense dislike of the know-it-all bookworm softens as Bo latches on to Raney, eager to learn about the Washington island he’s been sent for the summer.

Decades later Dr. Charlotte Reese finds herself fighting to keep an unconscious ICU patient stable while also unwrapping the mystery of the unconscious woman, the victim of a hit-and-run. Consumed by questions about the woman’s identity, Charlotte enlists Eric, her journalist boyfriend, to investigate. Their search for answers brings them to heartrending truths about Jane Doe―and themselves.

In beautiful interwoven storytelling, master of medical drama Carol Cassella presents two women—lifetimes apart—who face the inescapable forces shaping their lives. Filled with stunning medical detail and set against the breathtaking backdrop of the Pacific Northwest, Gemini is a vivid novel of moral complexity and emotional depth that “is just what the doctor ordered” (People).

Reading Group Guide

This reading group guide for Gemini includes an introduction, discussion questions, and a Q&A with author Carol Cassella. The suggested questions are intended to help your reading group find new and interesting angles and topics for your discussion. We hope that these ideas will enrich your conversation and increase your enjoyment of the book.


When an unidentified Jane Doe, the victim of a hit-and-run, arrives in Dr. Charlotte Reese’s intensive care unit, she brings with her mysteries—both medical and personal. As Charlotte cares for Jane, she becomes increasingly caught up in the questions of her patient’s identity and what led to her accident. Why has no one stepped forward to claim Jane? What will happen if she doesn’t wake up? When Charlotte’s search for answers reveals links between Charlotte and her patient, the repercussions will forever change her life and her understanding of what love can make possible.  

Topics & Questions for Discussion 

1. Why does Charlotte feel such a strong sense of responsibility for Jane Doe? How does she balance her protective feelings for Jane with her practical understanding of Jane’s prognosis?
2. From the moment she first sees Bo, Raney is acutely aware of the differences in their circumstances. How does her sensitivity about her background affect their relationship over the years? In what ways do they have more in common than she thinks? Why is their childhood attachment so enduring?
3. Charlotte sees her job as giving nature “as much time as possible” (117). In practice, what does that mean? How does it influence her feelings about Jane’s care and the appointment of a guardian ad litem?
4. How does the small town of Quentin, with its natural beauty and financial struggles, shape Raney’s life? In what ways does she identify as a small town girl, and in what ways does she resent that role?
5. Charlotte and Eric’s relationship is haunted by her desire to have a child, and his reluctance to do so. Why is the subject so difficult for them to discuss? Why does Charlotte feel they have stalled?
6. What reasons does Raney give for marrying Cleet? Would she have made the same decision if she were not pregnant? How is her understanding of love and loyalty shaped by her marriage to him?
7. How does Eric’s awareness of his neurofibromatosis, and the brushes with death it caused, influence his life? What choices does he make as a result? What boundaries does he lie down? Are his boundaries intended for his own protection or for others’?
8. As a child, Raney makes do with scavenged house paint for her art. How does that same make-do attitude manifest in her adult life?
9. What is the significance of Raney burning her paintings when her grandfather’s farm is sold? Why is this a turning point in her life as much as her grandfather’s?
10. Does Charlotte go too far by seeking David out and by trying to uncover Jake’s paternity? Does her involvement with Raney compromise her objectivity?
11. When she was a child, Raney’s grandfather taught her to light a campfire “with one match and her own wits” (229). Does Raney take his lesson about self-sufficiency to heart? At what points does she fail to follow his advice?
12. What prompts Raney to marry David? Why does she ignore her growing misgivings and stay with him? Do you think David was responsible for the hit-and-run?
13. Why do you think the author chose Gemini, the zodiac sign represented by twins, as the title of the novel? How does she develop the theme established by the title? What characters or events are “twinned”?
14. Gemini contains several mysteries: Jane Doe’s identity, whether the hit-and-run was accidental or intentional, Jake’s parentage, and others. Was there a particular revelation that you found most surprising or satisfying? What devices did the author use to maintain suspense?
15. Discuss the role of genetics in the novel. How does Eric’s “fatal flaw” link the characters? Eric wrote in his editorial that knowledge of your genetic code could be more damaging than helpful; is that true for Jake? Would you rather know if your genetics carried a “fatal flaw” or not?
16. Gemini raises challenging questions about our fear of death and our willingness to confront or discuss it. Did you react differently to Jane Doe’s situation than you did to that of Raney’s grandfather? How would you answer the question that Eric poses to Charlotte: “Should quantity of life always trump quality?” (9) Did reading Gemini stir you to look more closely at your own feelings about death?   

A Conversation with Carol Cassella 

1. What was the genesis of Gemini? Did you begin with an idea about a character or plot point? Or something else?  

After writing two novels told from a doctor’s point of view, I knew it was time to give the patient a chance to speak, so that was the first step in creating Raney. Then I needed to decide what the mystery would hinge upon and I turned to the world of genetics, which is rich with possible storylines.

As a mother of twins, and as a doctor, I’ve long been interested in how much of our lives is dictated by the genes we land here with—a blueprint over which we have no control. But my identical twins (who share the same DNA and upbringing, but have very different personalities), have also confirmed that who we are and how we respond to events in our lives is far more complex than either nature or nurture can explain.

Once I had those starting points decided, my characters began to emerge and the novel grew into a story that encompassed those elements, but also much more. Truly the most fun part of writing a novel is watching it take on a life of its own as it grows and changes over time.

2. In your first novel your main character was an anesthesiologist, your own specialty; in Gemini your main character is an intensive care physician. How did you approach writing from the perspective of this specialty? How are the demands of this job different from anesthesiology?  

Intensive care medicine and anesthesiology overlap quite a lot—they both focus on acute care situations rather than long term problems, and to do them well you need to love physiology—the mechanics of how the heart, lungs, kidneys, and liver keep us alive. They are both fast-paced patient care settings where things can change very, very quickly, so they tend to attract similar personalities. In fact, many intensivists begin with a residency in anesthesiology before doing a fellowship in intensive care medicine. So Charlotte’s work was more familiar to me than, say, a pediatrician’s or an oncologist’s. On the other hand, it has been years since I worked with patients who were as sick as Raney, and I depended on several ICU experts to get the details I needed. The biggest difference between the two specialties is that in the ICU the patients arrive very, very sick, and the intensivist has to try to turn that ship around. In the operating room, most of the patients arrive reasonably healthy—or at least stable—and our job is to keep them that way.

3. The title of the novel is the zodiac sign for twins. Why did you choose to highlight that theme?  

The title Gemini was suggested to me by an editor, so I can’t take full credit. It doesn’t fully make sense to the reader until the end of the book, when all the pieces of the mystery come together, but once you see the novel as a whole, the title seems perfect! The Gemini myth of Leda the swan and her twins Castor and Pollux—one mortal and one immortal—plays perfectly into Jake’s life, both biologically and metaphorically. But there are other “twin” stories at work in the novel, too: Raney and Charlotte, for all their differences, share similar personalities. They are both gritty, skeptical of the status quo, independent yet loyal to those they love. I imagine they would have been friends if they had been born into more similar circumstances. And in the course of the novel they are both faced with wrenching decisions about how far to go when caring for a terribly ill person they care about. I even saw Eric’s life in twin terms—the boy he was before his diagnosis usurped his belief that he could ever live a normal life, and the man he became afterward.

4. The settings of the novel help define your characters and contribute to the novel’s conflicts. Was it important to you to have parts of the novel set in the Olympic Peninsula? Did you base Quentin on a specific place?  

If you have visited the Pacific Northwest you know that our natural beauty is unparalleled. (Yes, I am prejudiced!) One day of sunshine here is well worth the ten days of rain that pay for it. It is such a joy to describe our landscape that I can never resist setting parts of my novel within it. But it also reflects much about Gemini’s characters and their conflicts—particularly Raney’s. The Olympic Peninsula, home to Olympic National Park and the rainforest, is completely unspoiled in areas, but many of the towns and the reservations are struggling with poverty and unemployment. In ways, it is only four hours but ten light years from Seattle. This has a huge affect on Raney’s life, of course. What would she have been able to do if she had been born into a more privileged family? How would that have changed the decisions she made?

On a more thematic level, contrasting the natural world of Raney’s woods and coast against the highly technical setting of an urban hospital’s ICU made a good backdrop for a novel that raises questions about natural death versus using every possible intervention at the end of life.

5. The novel deals head-on with moral and ethical questions about death and life, and when and how it should be extended by medical means. What prompted you to confront these questions? Do you find your own answers to these questions changing with new experiences from your work or life?  

I don’t think you can be a doctor in this day and age and not struggle with these questions. We have all seen miracles result from new medical discoveries and interventions—people who are given another chance to hold new grandbabies or hug their spouse. But we have also stood at the bedside of patients tethered to a ventilator, going through a long and drawn out death that none of us would want and which causes the patient’s family extraordinary grief. Too often we, the doctors, are to blame, because we weren’t strong enough to advise them honestly. And as medicine has become more complex, we need more and more specialists involved with critical patients, each focused on their own organ system rather than the complete picture. Sometimes families hear conflicting messages but no one physician is taking the time to listen closely, answer questions, and help them come to difficult decisions. It isn’t that doctors don’t care, it’s often that a rushed and fractionated healthcare system inadvertently neglects that hand-holding component. I often worry that we have raced forward in inventing medical marvels, but our ethical framework and guidance hasn’t had time to catch up.

More critically, though, in the last four years this question has become quite personal because several close friends and family members have become gravely ill or died. Being at someone’s bedside as a family member, rather than as a doctor, has had a profound effect on my thoughts about end-of-life care.

6. As our technological ability to extend the end of life increases, do you think understanding the implications of that ability is as challenging for doctors as it often is for individuals and families?  

Absolutely. We are approaching the question from different angles—doctors who are deeply invested in saving lives and becoming skilled in the tools that accomplish that, and families who are mired in grief, remorse, and longing as they struggle with end-of-life decisions. Only fifty years ago, less even, death happened more naturally. There was nothing we could do but console. Now we sometimes have to make very hard decisions, and the outcome of those choices isn’t always predictable. Will they lead to a few more days or months of good quality life, or a very uncomfortable, even more tragic death? These conversations are extremely difficult for doctors to initiate. They take time, and need to happen early and frequently, and there is little leeway in the fast-paced healthcare system to support that.

It’s critical for doctors to remember, though, that we must not only be shepherds of good health and long life, we must also be shepherds of good deaths. Death is not a failure—it is the natural and inevitable transition we all make at the end of our lives, just as we made the natural transition through birth into the beginning of life.

7. What sort of research did you do for the novel? Do you research as you write, or beforehand?  

The research for Gemini was extensive and broad—maybe that’s why my acknowledgments run two and a half pages! But I love that part of writing. Before I begin a novel, I have to know that the topic interests me enough to hold my attention and curiosity for the two or three years it takes to finish it. I spoke to neuroscientists, geneticists, intensivists, medical ethics specialists, forensic specialists, law enforcement officers, lawyers, and protective guardians. Then there’s the Internet, which can become a drowning ocean of valuable facts. I usually do several months of research in advance, which gives me the nuts and bolts of the mystery twists, then I augment that with focused research questions as plot points or dialogue need tweaking. I’m sure I still miss some details, but it is really important to me that my novels are grounded in solid science. While I want my novels to be entertaining, I also enjoy translating the fascinating world of medical science into words that anyone can understand and appreciate.

8. Your books always contain intriguing medical quirks or situations. Have you always been interested in these unusual details? Do you find yourself collecting them, making note of them for future books?  

The best part about medicine is the mystery—the challenge of taking a collection of symptoms and physical findings apart and tracing them back to the root problem—hopefully one we can fix. There are so many more mysteries in medicine than confirmed facts that it never gets boring, particularly when they involve all the social and emotional layers that affect our health and wellbeing.

I’ve been a fiction writer and reader since I was very young (though I didn’t fully dive in until my forties), so I tend to walk through the world looking for ideas. If some new and startling fact intrigues or puzzles me, I figure it will intrigue and puzzle readers, too, so I write it down or make a voice memo for later reference. Now if only I could live long enough to use them all. . . . Ah, but that dilemma goes right to the heart of this novel, doesn’t it?

9. Would you describe where and how you like to write? In the mornings or evenings? With music or without? How do you transition from parent or doctor mode to writing mode?  

Here is my ideal writing life: Every single morning I get up and put on my soft baggy sweat pants and fleece, make a huge latte, sit in front of the fireplace by the windows and let my imagination spin out on the keyboard for two or three hours before I tackle the less creative tasks of my life, such as email or those dirty dishes. Here’s the reality: I leave for the hospital at six and come home too tired to do anything but eat and go to bed, or (on the days I’m not in the operating room) I get pinged with critical meetings or messages about children, the business side of being a novelist, or the business side of medicine, and I’m lucky to get an hour or two somewhere in the day to create a bit of fiction. To compensate I often spend two or three days locked in a room where I do nothing but write.

Unfortunately I need total silence to write, though I love music and find it very inspiring. I usually try to take a break and go for a long walk or run with music, and I always come home with fresh ideas. Movement and exercise are important for generating creative work. It can be difficult to transition from parenting or doctoring to the quieter, inner world from which my stories arise. But that’s a problem all of us face, isn’t it? I’m so often asked how I balance the different roles in my life, but truthfully I don’t know many people—especially women—who aren’t constantly juggling all the obligations in their lives.

10. If there’s one thing you’d like readers to take away from Gemini, what would it be? What do you look for in fiction?  

A good book needs to linger much longer than the time it takes to read it. I want readers to come away from all my novels with more questions than answers—questions that spark conversations and richer internal thought about issues we all face. In Gemini, I’m hoping to spark a conversation about what, for each of us, constitutes a good and meaningful death. Those answers will be different for everyone, but they are key to another question I’m raising in these pages: What constitutes a meaningful life? How do we approach love and art and work, and our own definition of family, so that our lives are as rich and fulfilling as they can possibly be and we fully appreciate each of the finite days we are granted on this earth?
