After high-school junior Naomi conks her head, she can't remember anything that happened since sixth grade. This equally sensitive, joyful novel, her second for YAs, tackles the slippery nature of human identity, deceptively tucked within a plot familiar from TV soaps. *Starred Review* Contemporary realism, set askew, is the silver streak of Zevin, whose Elsewhere (2005) depicted a teen's experiences in the afterlife.

And fans of psychological dramas won't want to put this book down. Naomi, adopted in infancy from a Russian orphanage, can summon up more than enough hidden emotional depths to counterweight the slicker aspects of the story teens will identify with her vulnerability and her heightened feelings of alienation. Well-defined characters and convincing narration camouflage the Lifetime-movie premise and the inevitability of every plot turn (no one will doubt which characters will become romantically involved and who will end up together). The image of the boy-who helped her to the hospital and stayed to make sure she was all right-lingers as she tries to sort out her past and her feelings. What Naomi does remember is James, the first person she saw after her accident. Her best friend, Will, with whom she co-edits the school yearbook, and Ace, her tennis-player boyfriend, seem like strangers. She doesn't remember her parents' divorce (not to mention her mother's remarriage, her half-sister and her father's recent engagement to a tango dancer). Departing from the science fiction premise of Elsewhere, Zevin cooks up an entertaining love story out of what her narrator calls 'chance, gravity and a dash of head trauma.' As the novel opens, 16-year-old Naomi has fallen down a flight of stairs and lost all memory of the past four years.
