From New York Times bestselling author Margaret Peterson Haddix comes a novel about friendship and what it really means to be a family in the face of lies and betrayal.
Fourteen-year-old Avery Armisted is athletic, rich, and pretty. Sixteen-year-old Kayla Butts is known as "butt-girl" at school. The two girls were friends as little kids, but that's ancient history now. So it's a huge surprise when Avery's father offers to bring Kayla along on a summer trip to Spain. Avery is horrified that her father thinks he can choose her friends—and make her miss soccer camp. Kayla struggles just to imagine leaving the confines of her small town.

But in Spain, the two uncover a secret their families had hidden from both of them their entire lives. Maybe the girls can put aside their differences and work through it together. Or maybe the lies and betrayal will only push them—and their families—farther apart.

Margaret Peterson Haddix weaves together two completely separate lives in this engaging novel that explores what it really means to be a family—and what to do when it's all falling apart.
