Wyatt’s War by Elle James

She doesn’t want a glorified babysitter…until all hell breaks loose

Following a particularly tough deployment, Master Sergeant Wyatt Magnus is given a boondoggle assignment providing anti-terrorist security for an International Trade Convention in San Antonio, Texas. Convinced he’s in for a whole lot of boring hours, he’s surprised when he goes toe-to-toe with the feisty and sexy as hell convention director.
Fiona Allen has a difficult enough task corralling foreign dignitaries and pulling off a seamless itinerary. She doesn’t have time to handhold the far too arrogant and impossibly desirable Special Forces soldier assigned to her event by the Department of Homeland Security.

A hotel room double-booking lands them together in the same room. Her red-hot anger quickly turns to blazing desire. Giving in to one night of passion, she realizes will never be enough. But trouble is brewing in the form of a man on a mission of revenge, armed with hatred and enough explosives to obliterate the convention center and everyone inside.
