Call for Blood a historical fiction and action/adventure


In 1945, United States Army Counterintelligence Agent Jonathan Preston leads his King Cobra team, a group of determined Allied agents, through deadly jungle landscape and behind Japanese lines, parachuting into enemy territory, and dodging Japanese patrols.

Agent Preston doesn’t back down from even the deadliest missions and follows orders to lead a team of Allied operatives deep behind enemy lines in Southeast Asia to take on the Imperial Japanese Army’s Unit 731 — a frightening biological and chemical weapons component of the Japanese military responsible for the deaths of untold Allied prisoners of war.

After the King Cobra team succeeds in raiding Japanese prisoner-of-war camps and freeing hundreds of Allied soldiers, Preston and his colleagues must also evade a team of elite Japanese assassins hell-bent on their demise.

Call for Blood explores the little-known crimes and atrocities committed by the Imperial Japanese Army’s Unit 731 and gives readers a front row seat for one of the most fascinating dramas of World War Two.
A gripping story of good versus evil set in a dramatic theater of war, Call for Blood will leave you clamoring for more from author Steve Doherty.


Operation King Cobra a historical fiction and action/adventureOPERATION KING COBRA

A tidal wave of terror sweeps southern Asia after the Japanese capture Hong Kong and Singapore. When the U.S Army Chief of Staff implements Operation King Cobra and sends the highly trained and swarthy special missions agent, Jonathan Preston, into Asia, things begin to turn around. After Preston teams up with two British Special Operations Executive agents, Miles Murphy and Henri Morreau, the trio wreaks havoc on Japanese supply lines, foils sabotage and assassination attempts by Japanese agents, frees allied prisoners of war and begins shutting down the secret biological and chemical warfare programs of the Japanese Army’s Unit 731. After nearly a year of solid success, the top Japanese hit team is now after the Cobra trio. When the two teams collide, there is only one outcome: death.

Based on historical fact and real life accounts, Operation King Cobra takes you on a journey through some of the toughest terrain in Asia; following secret agents through dense jungles, over steep mountains, through crocodile filled rivers and into exotic ports of call. You’ll join some of the top secret missions that changed the course of the war in Asia and altered history. Be part of Operation King Cobra!
