In the small town of Ptolemy, darkness is a living thing. A powerful thing. Its home is in the shadows of a bizarre, hidden club named Penumbra, where it is worshiped by followers who need the pleasure it gives them. They are addicted to it. They live for it. And they kill for it.
Murder is the least of Penumbra's sins. The true terror is still to come when ... Darkness Wakes.
