Gallant by Melissa Combs

No escape. No turning back. And no resisting a storm of desire…
When Reno Arjona surfaces from a dive to discover he and his boss’s woman have been left behind, he knows one thing: he’s on his own. His undercover mission to bring down Vasco, a notorious Colombian drug lord, is too important to risk blowing his cover.
Once he tows Lacey Manning through miles of stormy ocean to a deserted island, all they have to do is wait. Because Lacey belongs to Vasco, and Vasco always comes for what’s his.
Since the moment she accepted Vasco’s friendly invitation for a drink, Lacey has lived in terror, an unwilling “guest” watched day and night. Only in her bodyguard’s arms, she feels safe. And on the island, there are no distractions from the forbidden sexual tension between them…
But the storm is only the start of the danger they’re in. And the only way to save Lacey may be to break his silence—and pray that when the bullets start flying, it won’t be friendly fire that destroys their hearts.
