Man Down (Wings of Gold, #3)
Tracy Tappan

Chased across northern Pakistan in a race for their lives, Jason and Farrin end up running from their own personal demons as much as from the enemy pursuing them. For Jason, being around his childhood friend, Shane, awakens unwelcome memories of an abusive past, while Farrin is haunted by a decision she made that forever changed her life.
In the midst of the chaos, both mental and physical, no one is more surprised by the attraction forming between Jason and Farrin than they are. Both have lived their lives closed off to relationships, unable to let go of the memories that haunt them. But just when they find the courage to move forward together, people from both of their pasts come back and threaten to destroy the new foundations of their love.
