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.

Poyer raises the bar with this one. The cave-diving scenes are riveting, claustrophobic, terrifying, and beautiful. - Booklist
