Critical Mass

In a deadly game of revenge, Kirk McGarvey becomes the target of a grieving man determined to make him pay the ultimate price.

Kirk McGarvey--one-time CIA assassin--dreams of a peaceful life and marital bliss. But one man will change all that. In 1945, Isawa Nakaruma lost his mother and father at Hiroshima, his wife and child at Nagasaki, and has been planning for years to wreak his revenge--and he holds Kirk McGarvey personally responsible.

Nakaruma's plan begins with the murder of McGarvey's girlfriend and the kidnapping and torture of his ex-wife and daughter. But he won't stop there, not until McGarvey himself is six feet under and nuclear bombs are detonated over Los Angeles and San Francisco.
