Seventeen year-old “Moxie" Crane's mother ruins her social life without ever stepping foot into her school. As if driving away her father and lying about it all these years isn't enough, Moxie's classmates discover her mother moonlights as a stripper, branding virginal Moxie with a reputation she can never live up to. Instead of getting upset, she gets tough, owning her outcast status and putting up a care-free front. But loneliness and a band audition advertisement lead her to Gavin Tully, a teen homeschooled for mysterious reasons who defies his parents’ strict rules to secretly start a band. They each have something the other wants: he's enamored by her free-spirit life, and she’s jealous of his overprotective, yet supportive family. Moxie teaches Gavin how to rebel and Gavin makes her feel like part of his family…until his parents catch them and force him back under their prison-like rules. Desperate to be a free spirit like Moxie, he takes the rebellion too far and runs away from home, leaving behind a breadcrumb trail of clues only Moxie can decipher. But when Moxie discovers his parents aren’t just strict…they're in hiding from a dangerous enemy, she sets out to find Gavin and rescue him the way he saved her.
