Will has never been outside, at least not since he can remember. And he has certainly never gotten to know anyone other than his mother, a fiercely loving yet wildly eccentric agoraphobe who panics at the thought of opening the front door. Their world is rich and fun- loving—full of art, science experiments, and music—and all confined to their small house. But Will’s thirst for adventure can’t be contained. Clad in a protective helmet and unsure of how to talk to other kids, he finally ventures outside. At his new school he meets Jonah, an artsy loner who introduces Will to the high-flying freedoms of skateboarding. Together, they search for a missing local boy, help a bedraggled vagabond, and evade a dangerous bootlegger. The adventure is more than Will ever expected, pulling him far from the confines of his closed-off world and into the throes of early adulthood, and all the risks that everyday life offers.
