Holes in the Ground (The Konrath Dark Thriller Collective Book 4.5)

Linguist Andy Dennison-Jones knows this all too well. He and his veterinarian wife, Sun, have been chased by them before, and barely escaped from a secret underground government facility with their lives.

Now they once again find themselves trapped alongside a collection of creatures straight out of hell. Fighting with them is an unlikely group of misfits, including a misplaced British kid, a former spec-ops soldiers, and a strange Irishman who might be the oldest living thing on earth—if he's even alive at all.

Filled with the kind of slam-bang action, wicked scares, and sly humor that have earned J.A. Konrath and Iain Rob Wright millions of fans, HOLES IN THE GROUND is both a collaboration and a continuation of both authors' previous work (ORIGIN by Konrath and FINAL WINTER by Wright) but also serves as a perfect introduction to their universes.
