As deaths mount, ex-sheriff John Decker is called from a much-needed vacation by a longtime friend, to help a baffled police department track an impossible enemy.

Grendel's Labyrinth: Under a ruined monastery near the quaint village of Clareconnell, a labyrinth of caves hides a dark secret. The remains of Grendel. Defeated by Beowulf and entombed there by the Danes, he has remained hidden for a thousand years, guarded first by warriors, then by monks, and finally by the villagers themselves.

But nothing stays lost forever.

A team of archaeologists is excavating the monastery and searching for his grave. Because Grendel’s bones may hold the key to a medical breakthrough that could change the world.

When John Decker, newly recruited to the shadowy organization called CUSP, arrives in the Emerald Isle to retrieve the bones, he discovers that there’s more to this idyllic village than meets the eye. For Clareconnell has a dark and shameful past, and now that the caves have been opened, the villagers must pay for their sins....

But it won't stay that way....

Within hours of the room's discovery, the body goes missing, and the murders begin anew.

With a violent killer on the loose and the body count rising, John Decker, still new to CUSP, is sent to England, along with seasoned operative Colum O'Shea. Their mission - to stop a ruthless monster from obtaining the one thing that will allow him to escape forever.

As the city huddles in fear and the terror mounts, Decker finds himself in a race against time to catch a hellish fiend smarter than any he has ever faced. Because if he doesn't, the next death might hit a little too close to home.
