When Ray Lilly was 13 years old, a handgun accident landed his best friend, Jon Burrows, in a wheelchair and turned Ray into a runaway and petty criminal. Fifteen years later, Ray returns home after a stint in prison; he's determined to go straight, but he knows he can't do that without making peace with his old friend.

What Ray doesn't expect is to discover that Jon has just received a mysterious cure–not only is he out of his wheelchair, he seems stronger and faster than... well, pretty much anyone. Worse, his cure has drawn the attention of all sorts of attention: the media are camped out on his block, the police are investigating him for insurance fraud, and weird shadowy figures have begun to draw closer, figures who clearly do not mean to do Jon any good.

Can Ray atone for the biggest mistake of his life by protecting his oldest friend? And what terrible price will the world have to pay if he succeeds?
