Risky Surrender (Take a Risk Series Book 2)

She'll search for treasure, but steal his heart. 
Lucy Davenport made a promise to her father and husband right before they died and she's vowed to keep it any cost. But when she draws unwanted attention to her secret plans, she's forced to risk everything she's kept guarded. Because the man standing in her way threatens not only her goal, but the walls she's carefully constructed around her heart.  
Keats McCall is an environmental preservationist navigating the globe on behalf of heritage protection. When he catches Lucy at his latest project, he suspects she's up to no good. She's secretive, sexy as hell--and has trouble written all over her. He devises a plan to keep her close so he can keep an eye on her. But what he isn't prepared for is just how close he wants to get.
