Viable Threat by Julie Rowe

Special Forces soldier and medic Walter River would give anything to snatch more than a few seconds of down time to see if he can rattle the no-nonsense and incredibly hot Dr. Lloyd he’s protecting, but dodging explosions, snipers, and student radicals who’ve unleashed a lethal bio-engineered microorganism have made that almost impossible. Maybe he’ll get a chance—if he can figure out how to keep them both alive.

CDC microbiologist Ava Lloyd races to find a cure for a bio-terrorism organism sweeping El Paso. The few stolen moments with her very hunky bodyguard River have been explosive, but no matter how alluring he is, she can’t afford to get distracted. The clock is ticking, people are dying by the hundreds, and once this crisis is solved, they’ll both be off on their next assignment, thousands of miles apart.
