Team Black Sheep by M. L. Buchman

The most dangerous mission of all: CSAR—Combat Search and Rescue. 

Sergeant Gerrard “Doc” Carson’s main claim to fame? Being the black sheep of his family. His solution to sign up as an Army grunt? About to cost him and his sharpshooter teammate Smith, and cost them bad. Hunkered down in Niger’s capital city during a coupe, his squad’s future is headed for that seriously permanent kind of Army discharge.  

When Medic Teri Carson and a full flight of the 160th Night Stalkers come to the rescue, he gets a new appreciation for the CSAR mission. But when “Doc” finds out Teri also holds the title of  Black Sheep, he knows he’s onto something special.
