Max Howarth is a 14-year-old high schooler with anorexia nervosa. Max lives in a small town in the west of England with his parents and his 21-year-old brother, Robin, an enthusiastic outdoorsman. About a year ago Max developed anorexia. His parents aren't sure how to help, but Robin cracks jokes and smooths over awkward situations. Robin also introduces Max to geocaching at Christmas, when the story opens. Max's two friends, Stu and Ram, know nothing about his anorexia because Max doesn't think they could possibly understand. He isn't honest with his therapist either, instead writing letters (interspersed throughout) in his secret journal to "Ana" (short for anorexia), telling "her" how she makes him feel. When his mother finds his journal, a terrified Max hides it in his geocache. When he returns for it he finds it's no longer there. In its place is a letter of personal confessions from "E," who he believes is Evie, the new girl at school. But is it? Pollen writes from the inside about anorexia, effectively communicating the feelings, obsessions, and difficulties Max experiences and making it clear that it is an equal-opportunity disorder. Ana's scornful voice frequently breaks into Max's narration, a device that combines with his meticulous calorie counting to place readers in his head. The book is default white, with nonwhite ethnicity primarily conveyed through naming convention; Ram is Muslim. A concluding author's note provides encouragement. Readers will appreciate the raw and real portrayal of anorexia from a group often left out of the conversation. (Fiction. 10-16)

For 14-year-old bird enthusiast Max Howarth, life is a challenge not only because he has family issues but also because he's anorexic. He thinks about food 16 hours a day, and despite all the knowledge he has about his illness, its grip grows increasingly tighter. His journal-addressed to "Ana," whose voice taunts him at every turn-is filled with his most intimate feelings about himself and the people and events in his life. Max's journal entries alternate with the narrative and teem with questions and emotions he can't otherwise express. One devastating emotion he wrestles with is loss. He feels his eating disorder is alienating him from his best friends. He also blames himself when his older brother moves out of the house and his parents' relationship shows signs of crumbling. It takes the attention of a new classmate, Evie, to bring Max's spiraling situation into focus and force him to decide to save his life. Max is a thoughtful, appealing narrator to whom readers will relate, and his story brings attention to an illness most commonly associated with girls and older teens or adults. This no-holds-barred debut novel based on the author's own experiences as a tween will be a significant addition to any library's middle-grade or teen collection.
