A terrifying force unleashed on the Irish countryside.

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 are 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...

This is book four in the John Decker series, but it can be read as a standalone novel.

If you are a fan of James Rollins, Douglas Preston, Lincoln Child, and Steve Alten, you will love the John Decker series.What Readers are Saying About the John Decker Series

¿¿¿¿¿ I have been looking for books like those written by Douglas Preston/Lincoln Child (since I devoured all of theirs) & I think I have found them! Hard to categorize.....part thriller, part suspense, part horror/supernatural, all good! - Goodreads Review

¿¿¿¿¿ John Decker is a "Monster Hunter" & I loved following his hunt for this monster! One way I judge a book is whether or not I will be looking for more by the author or in the series. This is definitely one that will add Anthony Strong to my TBR list! - Beverly Laude, Goodreads Review

¿¿¿¿¿ An exciting and fast-paced read! In the best traditions of Stephen King, Dean Koontz, Bentley Little et al, Anthony M Strong has delivered a rollicking read where alongside a well-told, thrilling story, you get fine characterization which makes you care about the people populating this tale! I would heartily recommend it - I am looking forward to reading more of his work... - F Dalgleish, Amazon review
