One ex-marine. One archaeologist. One secret map of a lost oasis. Searching for treasure is always dangerous, requires a lot of courage, and can end in death. However, this is all ideal for members of the Treasure Hunter Security Service. Former Marine Declan Ward is haunted by demons from his past and invests his life savings in a business protecting adventurers. Dangerous archaeological excavations are not a problem. Risky expeditions are always welcome. Securing museum exhibits is easy. But in Egypt, at the most ordinary excavations, Declan encounters a stubborn, intelligent archaeologist - Dr. Lane Rush, and together they begin a deadly hunt for the treasure of a mythical lost oasis. When the evil from Declan's past returns, he vows to do anything to protect Lane. Dr. Lane Rush has dedicated her life to her career, just as she promised to her parents, lost too soon. But when strange incidents begin at her digs and stolen artifacts end up on the antiquities black market, she is forced to turn to the Treasure Hunter Security Service, led by the rough, sexy, order-giving Declan. Soon, an orderly excavation turns into a frantic treasure hunt in the desert dunes. Danger lurks at every turn, and Lane and Declan must learn to work as a team... not only to find the treasure, but to survive.
