Chuck Brandt finds that a murky figure called Terminus is working behind the scenes to lure him into a trap. While he seeks to track down a deadly cargo, a cabal of assassins turns his existence into a world of explosive violence on the run, a high-stakes survival game to thwart a diabolical plot. The seedy worlds of Seattle and the Pacific Northwest become mazes of harrowing excitement where deranged obsession drives non-stop action and suspense."
