What are the rules of engagement in warfare? In pilanthrophy? In science? And in love? 
 
Scott Walker, a special ops soldier, knows there's a leak in his team, and rather than let loose to find the leak, he's put onto protection detail for two scientists - and he doesn't have time to be sweet. 
 
Cheyenne Keyes is a fresh-out-of-school low level and starry-eyed microbiologist working with men and women who've been stellar in in the field of genetic engineering. She gets to work with rabbit diseases, but, never despise small beginnings.
 
A scientist short, her work and his tactical abilities are married together to find the people behind the engineered common cold + Ebola virus, and to find a cure. 
 
Only Scott surprises Cheyenne, and Cheyenne freaks Scott out. However will they deal with this?!
