Twelve-year-old Carley Connors can take a lot. Growing up in Las Vegas with her fun-loving mother, she's learned to be tough. But she never expected a betrayal that would land her in foster care. When she's placed with the Murphys, a lively family with three boys, she's blindsided. Do happy families really exist? Carley knows she could never belong in their world, so she keeps her distance.

It's easy to stay suspicious of Daniel, the brother who is almost her age and is resentful she's there. But Mrs. Murphy makes her feel heard and seen for the first time, and the two younger boys seem determined to work their way into her heart. Before she knows it, Carley is protecting the boys from a neighborhood bully and even teaching Daniel how to play basketball. Then just when she's feeling like she could truly be one of the Murphys, news from her mother shakes her world.
