Primary Threat

"One of the best thrillers I have read this year."

--Books and Movie Reviews (re Any Means Necessary)


In PRIMARY THREAT (The Forging of Luke Stone—Book #3), a ground-breaking action thriller by #1 bestseller Jack Mars, elite Delta Force veteran Luke Stone, 29, leads the FBI's Special Response Team as they respond to a hostage situation on an oil rig in the remote Arctic.


Yet what at first seems like a simple terrorist event may, it turns out, be much more.


With a Russian master plan unfolding rapidly in the Arctic, Luke may have arrived at the precipice of the next world war.


And Luke Stone may just be the only man standing in its way.


PRIMARY THREAT is a standalone, un-putdownable military thriller, a wild action ride that will leave you turning pages late into the night. The precursor to the #1 bestselling LUKE STONE THRILLER SERIES, this series takes us back to how it all began, a riveting series by bestseller Jack Mars, dubbed "one of the best thriller authors" out there.


Books #4-#6 are also available!


"Thriller writing at its best."
