Vengeance (Wounded Heroes #4)
Anne Patrick

Thrown into the volatile situation are the personal struggles of Nick and Hope. Nick, suffering from PTSD, is a powder keg ready to explode. Hope, facing her own demons, is his lifeline to sanity. She has to convince him he needs help or their whole world might come crashing down. Nick is a proud Ranger though. Admitting his weakness could destroy the respect and trust of the men who depend on him. It's not a risk he's willing to take.
