Sweepers - P. T. Deutermann

Sweepers is a novel about revenge left to grow very cold indeed.  A navy seal named Galantz, who isn't picked up on the river bank in Vietnam.  A navy lieutenant named Sherman who left the seal behind when under attack.  Over 20 years later the seal becomes a sweeper and the lieutenant becomes an admiral.  This book paints an intricate tale of lies, love, deceit, and murder.  As always Deutermann's story grabs the reader and won't let go.  Very highly recommended.
