The Protector of Ambra (Mercenaries of Fortune #5)

An ill-tempered chocolatier, a Navy doctor and a trip to paradise with more guns than he thought he’d need.

When feisty chocolatier, Melody Thompson, files down to Mexico to corner her thieving business partner, she finds unexpected help from a hunky doctor with some secrets of his own.

Navy doctor turned treasure hunter, Pierce Hamilton, needs a little excitement in his life. When a slightly unapproved leave of absence lands him in a shootout in Mexico, the only thing making it half-worthwhile is a hottie with a bad attitude.

Alone, they're in trouble. Together, they're swimming in it. As both their enemies emerge and secrets unravel, the unlikely duo search for protection at each other's backs and try to avoid the sparks ignited in each other's arms.
