Fleeing assailants through deserted alleyways, Thomas Hunter narrowly escapes to the roof of a building. Then a silent bullet clips his head, and his world goes black. But from that blackness comes an amazing reality: another world where evil is contained, and Thomas is in love with a beautiful woman. While he's in that world, though, he remembers-as if it were a dream-being chased through those alleyways. And every time he falls asleep, he moves between worlds, awaking in the other. Now, in both, he finds that catastrophic disaster awaits him-and may even be caused by him. As the fate of two worlds depends on his choices, he's left to wonder: where does the dream end and reality begin?
