When thirteen-year-old Lily Chen wakes up in her childhood bedroom with nineteen years of memories that shouldn't exist, she knows exactly what's coming: the day her parents bring home Maya, the adopted daughter who will slowly erase her from the family. Armed with impossible knowledge of the future, Lily is determined to stop begging for love from parents who will never choose her—this time, she'll become untouchable and make them see what they threw away. But when she tries to prove her rebirth is real, her own diary becomes evidence of delusion, and her desperate attempts to save herself only convince her family she's dangerous. As her parents move from boarding school threats to psychiatric hospitalization, Lily discovers that surviving her family twice means accepting a devastating truth: some people will never believe you, even when you're telling the impossible truth. Now she must decide whether proving she died and came back is worth losing everything all over again—or if the only way to win is to stop fighting for a family that buried her long before she actually died.
