Nobody's Hero - The Protectors, #4

Sam Cooper has done his time on the hero circuit. First as a Navy SEAL and then as an FBI agent, Cooper learned how easily a man could stumble on that path. Now he's nobody's hero, a PI living on his boat and working cases where the only thing at stake is money. Then Jessie Burkett shows up on his dock, insisting he help find her missing sister, Nicole. Although all of Cooper's instincts scream at him to set sail for the wide-open waters of the Caribbean, he can't turn his back on the stubborn woman whose captured more than his professional interest and leave her to the ruthless men surrounding her.
Soon, he's once again following a hero's path, but in his search for Nicole, he's made some powerful-and deadly-enemies. Worse, he can't seem to keep his hands off Jessie. Right now he's her knight in shining armor, but will she still want him when she no longer needs a hero?
