After a family tragedy, Kate Donnelly left the Caribbean behind forever. But a series of bad management decisions has left her family's diving and treasure-hunting business drowning in red ink. Now her brother pleads with her to come back to the island of St. Vincent and offer her financial expertise. Holden Cameron was addicted to the adrenaline rush of active duty-including narrowly surviving an underwater explosives accident. The last thing the former British military diver wants is to babysit a family of thieves on a tropical island-even if they are the world-famous Diving Donnellys. When equipment, treasure, and even divers begin to disappear, Kate and Holden form an uneasy alliance to uncover the truth. But the deeper they plummet into the mystery, the closer they come to one another. Soon they are sharing their deepest fears and darkest secrets-and a combustible chemistry too hot to ignore.
