Craig Lockman has always protected the world from evil. Battled wicked creatures with an unquenchable thirst to destroy our world. Stood against the darkest of the darker things.

Now his most dreaded enemy lurks closer than ever before.

It's a horror he's not prepared—much less equipped—to fight. And if he doesn't prevail, the future of everyone he loves will fall into darkness.

For the first time in his life, Lockman feels afraid.

He is about to face his darkest hour.
