In this “truly rare book” (The New York Times) an attractive young woman imagines herself autonomous and self-sufficient, only to discover that she is unwittingly entrapped in “the lives of the twins.”

Molly Marks can’t make up her mind. Switching plans of study, bouncing from job to job, she feels lost. But all that might change when she begins a relationship with a young psychiatrist. Handsome, successful, and caring, Jonathan is the first person (apart from herself) Molly has ever cared deeply about. There’s just one sliver of doubt: Jonathan’s refusal to talk about his twin brother. Determined to uncover the reason behind his silence, Molly arranges a secret meeting with the estranged brother named James, also a psychiatrist.

After this reckless act, Molly embarks on a dangerous double life as her relationship with both brothers becomes more and more tangled. She questions whether she can trust either man—or even herself. The first mystery novel Joyce Carol Oates wrote using the pen name Rosamond smith, Lives of the Twins is a suspenseful psychological thriller with a dark family secret at its center.
