Darian Cole, a retired special forces operative, takes a commission from Vincent Calvo, a powerful New York Port mafia boss, to raise money for his mother's surgery: to sail out and retrieve Isabella, Calvo's only daughter who went missing on the high seas. Darian rescues Isabella from pirates on an abandoned cargo ship, setting off a death-defying journey across the Caribbean. The spoiled mafia princess initially looks down on the rough mercenary, yet cannot resist the dangerous, primal pull he exerts—while Darian, in turn, develops an uncontrollable urge to protect the temperamental heiress. The two hang by a thread through pirate hunts, shark attacks, shipwrecks and adrift, and rival gang sieges, forced to surrender their trust and true feelings in the face of certain death.
After returning to New York, Darian is hired as Isabella's personal bodyguard to dig into the truth behind her disappearance. As the investigation deepens, it points directly to the rival mafia family, the Massaris. Operating under the cover of port cargo, they have built a transatlantic human trafficking network, smuggling women and laborers like livestock to South America and Africa. But the deadliest truth lies buried in Darian's own bloodline—he is the sole survivor of Nico Corvara, the legendary mafia godfather whose family was massacred in a setup by the Massaris twenty-five years prior. The old family massacre, his mother's life on the run under a false identity, and the forbidden love between him and Isabella that neither family will allow—all the grievances converge into a one-way path of no return in blood and fire. He is going to settle old scores and new, all at once.
