But Rory isn't prepared when he suddenly and inexplicably turns green and finds himself stuck in an experimental hospital ward. The doctors are just as baffled as Rory is, and that's when he begins to wonder: What if this isn't caused by his genes, or a virus, or something he ate? What if it's something even more extraordinary? After all, more than a few superheroes' careers began when they turned green. Could this be a sign that he's meant for something greater? Rory is going to find out—and that's going to start with escaping from the hospital.

Frank Cottrell Boyce, the acclaimed author of Millions and Cosmic, has written another modern classic, a funny, whimsical, and heartwarming story about the ways in which so many of the things we see in others are rarely only skin-deep.
