FREE: Deadlock by Iris Johansen

The back says: Emily hudson is a renowned archaeologist who travels the world to save priceless artifacts from theft or destruction. Her best friend and partner, Joel Levy, is always at her side--until one day, when her entire crew comes under attack. Joel and Emily are taken hostage by a sadistic captor who is determined to find the missing link to a legendary treasure. For weeks they struggle to survive against terrifying odds, pushed to their limits--and beyond...
John Garret has worked for the CIA, British intelligence, and whoever else was willing to pay for his services. This time, a Washington operative hands him what at first appears to be just another assignment to track down, and save, Emily and Joel. But it quickly becomes much more, especially when Garret finds himself drawn to someone as dauntless and bent on revenge as Emily. Soon, they're catapulted into an astonishing adventure in which nothing--and no one-- is what it seems. And lives hang in the balance as one man and one woman unravel the explosive truth behind a conspiracy hidden for generations.
