From back of book:
In the chaos of Bosnia, U.S. Navy SEAL Chief Ted "Grim" Reaper disobeyed a direct order from a corrupt superior officer, hoping to prevent a massacre. And he paid with his career. Forced to retire or face court martial, he left the military life. Reaper thinks his fighting days are over, until a hated face from his past walks into his gunship to strongarm him into accepting an illegal shipment of weapons.
This book is written by Dennis Chalker, USN (Ret) Commander Master Chief. He was a founding member of SEAL Team Six.
