Harper's dad is divorcing her beloved stepmother, Jane. Even worse, Harper has lost her stepsister, Tess. The divorce divides them, just when her best friend Gabriel betrays her. Harper decides to get away for the summer and joins a volunteer program to build a house for a family in Tennesee who lost their home in a tornado. (Not that she knows a thing about building a house.) Soon she's living in a funky motel and laboring long days in blazing heat with a quirky, terrific group of kids. Working alongside Teddy, the son of the family for whom they are building the house, Harper and Teddy's partnership turns into a summer romance. Learning to trust and love Teddy isn't easy for Harper, but it's the first step toward finding her way back home.
