Finding undiscovered treasures is always daring, dangerous, and deadly. Perfect for the men and women of Treasure Hunter Security.

After a mission gone terribly wrong, former Navy SEAL Hale Carter has made a good career for himself at Treasure Hunter Security. He gets to use his engineering skills designing new gadgets, his SEAL skills providing security for exciting expeditions and treasure hunts, and he enjoys a variety of ladies on his downtime. He might still be plagued by nightmares, but all in all, life is good. Then he volunteers for a dangerous undercover mission into the Kalahari Desert, alongside a cool, attractive FBI agent who challenges him at every turn.

Special Agent Elin Alexander is driven to bring down the deadly black-market antiquities ring Silk Road. She's experienced firsthand how they destroy lives and she's vowed to end their greed and killing. After months of undercover work, she's eager for the mission to find the Lost City of the Kalahari. What she wasn't expecting was six-feet-three inches of former Navy SEAL as her partner. Hale is too handsome, too sexy, and isn't inclined to follow orders.

As the pair infiltrate the Silk Road hunt, Hale and Elin find themselves fighting a scorching attraction as they work to discover just what the lost city is hiding. But stuck in the bowels of a legendary ancient mine, Hale and Elin must put their trust in each other, to not only save the day, but to get out alive.
