'There are monsters among us. There always have been and there always will be. I've know that since I can remember, just like I've always known that I was one . . . Well, half of one anyway.' Cal Leandros is 19. He eats junk food, he doesn't clean up after himself and fights with his half brother Niko. It's a fairly normal life, but for the fact that Cal and Niko are constantly on the run. Cal's father has been after him for the last four years.
