Publisher's Summary

Welcome to the most dangerous sport on Earth: Where cave divers step into murky Florida ponds and end up hundreds of feet below the ground, threading through the narrow passages of Swiss-cheese-like rock formations, heading down tunnels that may open into caverns of breathtaking beauty, or else suddenly collapse in rockfalls that crush out their air and their lives.

Open-water diver and ex-con Tiller Galloway has come to this watery underworld to find out why an old friend died young - and take one last shot at being a father, a lover, and a friend. But with a woman opening up her heart, and a deadly conspiracy closing in around him, Galloway must navigate between lies told aboveground and truths hidden in the depths...where a violent battle is about to explode.

Combining the knife-edged action of Clive Cussler with the heart stopping storytelling skill of John D. MacDonald, USA Today best-selling Dave Poyer continues to be one of American’s most popular and remarkable thriller writers...and a master of underwater suspense.

“Fans of Clive Cussler will love this thriller. An essential purchase.” (Library Journal)
