The Rhythm of Evil

2020, A Reggie Decker mystery.

I always enjoy the twist in the plot DENNIS so aptly weaves into his stories. Can’t wait for the next one to come out ~ CAPT Jerry Rovner, USN (Ret.)
. . . He pulls from current events the very mysteries of today and weaves them into his intriguing story, leaving you breathless . . . ~ CAPT M. Kris Carlock, USN (Ret.)
The Oath, by Dennis Koller

The Oath

2016, A Tom McGuire thriller.
$14.99; Also available as audiobook

Excellent book, lots of suspense. I was born in San Francisco and served in the Navy during Vietnam, therefore I can relate to the environment and the revenge against the US traitors. ~ Raymond J. Fazzio
. . . The procedural part fascinates me even if I know the ending. In the case of Koller’s book “The Oath” the characters are vivid and living people. Some of them are thinly disguised avatars for people that were and still are in the public eye. . . To those who remember the era and remember the controversies involving Jane Fonda, this novel will bring back memories. I don’t want to spoil the plot by saying any more. It’s a good read. ~ MCCS Robert Hansen, USN (Ret.)

The Custer Conspiracy

2016, A Tom McGuire thriller.

Lots of action that keeps you turning pages to see what comes next. If you like history and conspiracies, this is for you. ~ Kyle, sniper, Sergeant, USMC (Ret.)

Kissed By The Snow

2014, A Rob Kincaid thriller.

If you liked The Oath, you’ll be glad to know that Tom McQuire and his wife, Michele, remain a constant in Kissed By The Snow, a new series with a former Navy SEAL, Rob Kincaid, as head of a security firm. Rob’s firm has contracts with the federal government to handle assignments that require plausible deniability. When the government seeks to do “the greater good” despite the collateral damage, watch out! If you thought Fast and Furious was an ill-thought out scheme by the government to track illegal gun sales among the Mexican cartels, wait until you read what it does to end the War on Drugs in Koller’s first book in the Rob Kincaid series. I look forward to reading his next installment in the series. A satisfying and interesting read. ~ CAPT Michele Lockwood, USN (Ret.)
