Daybreak is a graphic novel like no other that I have read. It brings the reader into the story as one of the characters. You wake up to find the world a very different place. A mysterious one armed boy greets you and you realize that you and he are some of the last people alive. Everything around you is rubble and ruins. The boy takes you to a safe, underground space where you rest. Later you venture out and find the world overrun by zombies. This post-apocalyptic thriller slowly builds the tension with letting the threat of danger be the driving force rather than actual carnage.
