Blake Thornwood never expected the apocalypse, but when it came, he was ready. In a world filled with monsters, he's doing the only thing he can: survive. That survival includes learning more about the mysterious cards the sytem is granting random people. Revelations start to pile up, and it's revealed that he has a unqiue ability among Earth's citizens. He can access the heart of the cards, drawing out their true powers.

If Blake can survive long enough, he might find out not only the origin of the system, but also his own origin. The truth, however, is something that will shake the foundations of both Blake Thornwood and the system itself.
