In Primary Threat (The Forging of Luke Stone, Book 3), a ground-breaking action thriller by number one best seller 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 listening late into the night. The precursor to the number one best-selling Luke Stone thriller series, this series takes us back to how it all began, a riveting series by best seller Jack Mars, dubbed "one of the best thriller authors" out there.

Also available is Jack Mars' number one best-selling Luke Stone thriller series (seven books), which begins with Any Means Necessary (Book 1), which has over 800 five-star reviews!
