Debra’s Protector by Janie Crouch

Your past will find you, even on an island paradise…
At forty-six, Debra Wheeler is thriving in her dream job as the manager for the Ellington Cove resort in Key West. Brick by painful brick, she’s built a life she can finally be proud of.
But when an old acquaintance blackmails her–demanding access to the resort guests’ valuables–protecting herself means revealing her worst mistakes to the resort’s special security team.
Including sexy silver fox Wes Slater.
As the new face in town, Wes is uniquely equipped to help Debra with an undercover operation to bring down the criminals. He’s got the military and security background to handle it.
Even if fifty feels too damned old to pretend to be someone’s boyfriend—he’s about to become a grandfather for God’s sake. But he’ll do whatever it takes to help prove the innocence of the gentle beauty he can’t get out his head.
When the danger turns deadly and the fake relationship turns into very real feelings, two people who thought passion had already passed them by will find it’s never too late for love.
…if they can stay alive long enough to enjoy it.
