Lily has lived with her mom since her parents got divorced several years ago, and her dad has recently remarried to a woman with a daughter her age named Hannah. But now, Lily's mom has gotten a once-in-a-lifetime work opportunity in Africa and she'll be gone for a year, so Lily is moving in with her dad--and new stepmom and new stepsister. It'll be as easy as apple pie, right?
Wrong. Lily promises her dad that she'll try to get along with everyone, but she is not happy about it. Her stepmom is nice, but she's no replacement for her real mom, and Lily feels like she barely gets any one-on-one time with her dad anymore.
The real problem, though, is Hannah. What starts out as tension between the new stepsisters becomes a full-on war, both at home and at school. Harmless pranks turn into total sabotage. Can Lily survive the year--or is her family fractured beyond repair?
