Samuel Marquis is a bestselling, award-winning suspense author. He works by day as a VP-Hydrogeologist with an environmental firm in Boulder, Colorado, and by night as a spinner of historical and modern suspense yarns. He holds a Master of Science degree in Geology, is a Registered Professional Geologist in eleven states, and is a recognized expert in groundwater contaminant hydrogeology, having served as a hydrogeologic expert witness in several class action litigation cases. He also has a deep and abiding interest in military history and intelligence, specifically related to the Golden Age of Piracy, Plains Indian Wars, World War II, and the current War on Terror. His first two thrillers, The Slush Pile Brigade and Blind Thrust, were both #1 Denver Post bestsellers for fiction, and his first three novels received national book award recognition. The Slush Pile Brigade was an award-winning finalist in the mystery category of the Beverly Hills Book Awards. Blind Thrust was the winner of the Foreword Reviews' Book of the Year (HM) and the Next Generation Indie Book Awards and an award-winning finalist of the USA Best Book Awards and Beverly Hills Book Awards (thriller and suspense). His third novel, The Coalition, was the winner of the Beverly Hills Book Awards for a political thriller. Ambassador Marc Grossman, former U.S. Under Secretary of State, proclaimed, "In his novels Blind Thrust and Cluster of Lies, Samuel Marquis vividly combines the excitement of the best modern techno-thrillers, an education in geology, and a clarifying reminder that the choices each of us make have a profound impact on our precious planet." Former Colorado Governor Roy Romer said, "Blind Thrust kept me up until 1 a.m. two nights in a row. I could not put it down. An intriguing mystery that intertwined geology, fracking, and places in Colorado that I know well. Great fun." Kirkus Reviews proclaimed The Coalition an "entertaining thriller" and declared that "Marquis has written a tight plot with genuine suspense." James Patterson compared The Coalition to The Day After Tomorrow, the classic thriller by Allan Folsom. Other book reviewers have compared Book #1 of Marquis's World War Two Trilogy, Bodyguard of Deception, to the spy novels of John le Carré, Daniel Silva, Ken Follett, and Alan Furst.
