Two elite snipers. One deadly vendetta.
When an L.A. detective is assassinated from over two and a half miles away, ex-Marine turned musician Nicholas Sharp investigates. Only one man could have made that shot—except he’s already dead. As the killer threatens Sharp’s inner circle and targets the U.S. Secretary of Defense, he’s plunged into a blood-soaked conspiracy tied to the darkest chapter of his past. Faced with a diminishing chance of survival, Sharp must take down the only enemy who can match him.
But how do you beat a killer who knows your every move?
Somewhere between Ludlum’s Jason Bourne and Clancy’s Jack Ryan, Nicholas Sharp may be a flawed and reluctant hero, but you sure as hell want him on your side.
COUNTERPOINT is a great introduction to both the Nicholas Sharp and Lachlan Byrn Thrillers.
