One shot ruined his life. One mission could end it. 

After false intel causes him to execute an innocent man, elite sniper Nicholas Sharp quits the Marines. He trades his rifle for the piano, becomes a successful musician, and moves on—until a close friend vanishes. Blackmailed by his corrupt former commander, Sharp is forced to locate a hidden cache of chemical weapons while on a USO concert tour of Iraq. But he gave up following orders long ago. Navigating a deadly maze of colliding worlds and dark agendas, Sharp orchestrates a daring rescue. 

He knows there’ll be blood on his hands. It’s just a question of how much… 


Somewhere between Clancy’s Jack Ryan and Ludlum’s Jason Bourne, Nicholas Sharp may be a flawed and reluctant hero, but you sure as hell want him on your side.
