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 drowns in panic at the thought of opening the front door. Their world is rich and loving, full of art, experiments and music --- but 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. With the help of an artistic loner who introduces Will to the high-flying freedom of skateboarding, Will is pulled far from the confines of his closed-off world and thrust headfirst into the throes of early adulthood and the dangers that everyday life offers.
