Irkalla

Jason and Penny Beringer lead a small cave diving team in a daring bid to become the first explorers of a newly discovered system of underwater caverns hidden deep in the Philippine jungle. But within this maze of sunken chambers lives a genetically engineered predator, a creature capable of spreading havoc on both land and beneath the lightless, suffocating depths of this mysterious underworld.Combining tense, white knuckled thrills and scientific horror, John Triptych's newest release will surely interest fans of Michael Crichton, Peter Benchley, and Clive Cussler.
