Adam's summer is off to a disappointing start. His so-called "best friend" has bailed on him, choosing to stay behind to care for a sick dog, instead of joining Adam and his family at the seaside campground as planned. Adam is furious with Billy for abandoning him, impatient with his mother for her artistic obsessions, and embarrassed by his dad's lame attempts at being funny. At least an ever-changing cast of new summer friends proves to be an entertaining distraction: Joey, the shoe-thief with the cute sister; the mischievous Linden twins; enigmatic Nevin; and Ethan, the adventurer. But it is Theo, the blind gentleman up on the hill, with his magical stories of driftwood, who helps Adam to see the true nature of friendship-and find the path to forgiveness.
