Hell or high water

the long version

"Only two things could make former Navy SEAL Leo Anderson return to the world of weapons and warfare. First, a capsule of chemical weapons lost on the ocean floor, and second, a plea for assistance from the one woman he can't seem to forget--CIA Agent Olivia Mortier. Now, working together to race against the clock and a deadly terrorist faction, Leo and Olivia must find the missing capsule, all the while battling the intense desire burning between them. If they can survive, can their growing attraction become more than just a momentary flare?"--
