Stephen Hunter: Point Of Impact [2003] paperback

In the jungles of Vietnam, Bob Lee Swagger was known as 'Bob the Nailer' for his high-scoring target rate at killing. Today the master sniper lives in a trailer in the Arkansas mountains, and just wants to be left alone. But he knows too much- about killing. The mission is top secret. Dangerous, patriotic, and rigged from the start. One thing goes wrong: double-crossed Bob has come out alive. Now he is on the run. His only allies: an FBI agent in disgrace and a beautiful woman. His only hope: find the elusive mastermind who set him up. Multi-layered with non-stop action, this hot-shot torcher of a thriller is addictive, exciting and right on target. A high-tech, high-ride reading experience.
