The boy stepped Outside, and he did not die. Will has never been Outside, at least not since he can remember. For most of his young life he has lived happily – and safely – Inside his small house with his mother, a fiercely loving yet wildly eccentric agoraphobe who panics at the thought of opening the front door. But Will’s curiosity can’t be contained. Clad in a hockey helmet to protect himself from unknown dangers, he finally ventures Outside – and braces himself for disaster. What he finds instead will change everything.
Will embraces his newfound freedom and soon befriends Jonah, an artistic loner who introduces him to the high-flying thrills of skateboarding. But life Outside quickly grows complicated. When a local boy goes missing, Will is pulled further away from the confines of his closed-off world and thrust headfirst into the throes of early adulthood and the criminal underbelly of city life. All the while his mother must grapple with her greatest fear: will she be brave enough to save her son?  
In dazzling, kinetic prose, Michael Christie has written a beautifully tender and emotionally resonant story about family and friendship, overcoming our fears, and learning when to protect the ones we love and when to let them fall.
