Ten-year-old Lexie used to love going to the shore. For as long as she can remember, she's spent every summer there with her parents, eating hamburgers, swimming in the ocean, and combing the beach for treasure.  This summer is going to be different though. Lexie's Mom and Daddy are divorced, and for the first time Mom won't be there. To make matters worse, Daddy has a surprise—his new girlfriend, Vicky, and her two sons are coming to stay with them for a week!  Now Lexie has to share her house with perky Vicky, Vicky's moody teenage son Ben, and messy three-year-old Harris. The little beach house just doesn't seem big enough for so many people. Is there still room for Lexie?

In a voice that's sharp, funny, and sincere, Newbery Honor-winning author Audrey Couloumbis tells the story of a girl discovering that if you pay attention, sometimes you can find treasure in the most unlikely places.
