Ever since she was li little, Rhiannon has lived with her aunt in a sleepy, sun-drenched trailer park called Golden Canyon Retirement Community. Growing up among senior citizens, Rhia is usually the only kid around-except during the summer. That's when her best friend, Kit, comes for a long visit. This summer, something has changed. Rhiannon and Kit's easy friendship is no longer easy. Even worse, there's a new teenager in the park-Elizabeth. She's the polar opposite of Rhiannon: hip, confident, and a bit of a troublemaker. And Elizabeth has a secret that will put Rhiannon and Kit's friendship to the test.
