When Denver is plagued with zombies and stalked by a serial killer, it's the toughest case yet for Kal Hakal of the Bureau of Supernatural Investigations.

Kal Hakala is the Bureau of Supernatural Investigation's top man, the longest surviving agent in its blood-soaked history. A childhood encounter with a legendary monster left him with endless hatred for all things Supernatural, a sentiment he puts to use in his work. There has never been a case Kal couldn't crack, or a monster he couldn't kill. But no winning streak can go on forever . . .

When a plague of zombies comes to Denver, along with a vicious serial killer known as The Organ Donor, Kal once again goes on the job. But now the target is on his forehead. The World Under has gotten wise to Kal's tricks, and the Un-Dead are proving especially hard to kill. The Bureau has a few aces up its sleeve, including a few magicians and a cyber-ghost. Now Kal, the perpetual loner, may have to learn to play nice if he wants to live long enough to see these monsters die.
