His first priority: follow the leads in the case. Then he can go about the all too enjoyable task of following his heart.

But when a legendary amulet is stolen practically from under her nose, she needs the help of her nemesis, archaeologist Harrison Standish. No-nonsense Harrison has all the intensity of Indiana Jones. Though just when he needs his full attention on their mission, he's having the damnedest time keeping his mind and his hands off Cassie.
