Herc's Mercs: The Collection Volume 3. Herc's Mercs, #3

ABOVE AND BEYOND.No matter where in the world they have to go, the men of Hercules Security are ready to kick ass, take names, and, above all, save lives. Putting themselves in harm's way is second nature to these men, and they'll do whatever it takes to protect the innocent. Unfortunately the cost of such bravery is often brutally high, and sometimes the price a hero must pay isn't always obvious.Hunter Callahan loved his job as an explosives expert, but when a seven-year-old boy walks into camp wearing a suicide vest, the explosion that rocks Hunter's world leaves him with wounds too deep to see with the untrained eye.
Payne "Pita" Gibson is the only one who stands a chance of saving Hunter from self destruction, but doing so means Payne must share private facets of his own life. Could his unusual form of therapy not only help Hunter, but also win his heart? Pushing Hunter's limits so hard is a test of Payne's own strength of will -- but everyone knows that it's No Pain, No Gain.
