About this book

Jonathan Grave is a covert rescue specialist who operates outside the law for powerful clients who need discreet help. He works with no names, no federal involvement, and leaves no trace evidence. His expertise lies in handling highly sensitive hostage situations. When an Indiana college student is abducted, Grave and his team of operatives investigate and uncover a deadly scheme that the government wants kept hidden. At the center of the case is a devastating secret that someone wealthy and powerful is willing to kill to protect—including those closest to Grave.
