Jason never wanted power or responsibility, and never wanted to kill. All he ever wanted was a normal life with his wife and daughter. But when the all-consuming mass known as the Growth arrives, everything changes. It ravages the land and unleashes monstrous creatures to hunt down and kill humanity. Amid the chaos, the Guardian is released, and Jason is bestowed with powers he never asked for to fight in a war he wants no part of. However, with his family threatened, he has no choice but to fight. With only a few allies at his side, Jason is forced to confront his fears and the ghosts of his past as he battles the monsters of the present. Will he be able to stop the Growth and prevent humanity's extinction, or will he make the same mistakes all over again, losing himself in the process? The Doomsday Clock is ticking, and only Jason can prevent it from reaching its conclusion at the end of The Eleventh Hour.
