On the Edge — Kerry J. Donovan

Ryan Kaine is on the edge….

Lara Orchard is on a mission to prove herself.

Convincing her partner, Ryan Kaine, that she needs combat medical training, they fly to Denmark under assumed identities.

Kaine is on high alert, keeping a watchful eye on her throughout the course -- but it's not her medical skill he's worried about.

Despite knowing the gunfire and the bombs aren't real, Lara struggles to control her fear, but leaves herself exposed to a threat she doesn't see coming. In a desperate attempt to protect her, and breaking his own moral code and a few bones, Ryan Kaine is pushed to his limits…

If you like Lee Child, Mark Dawson and Robert Ludlum, you're going to find the Ryan Kaine series compulsively addictive.
