“One of the best thrillers I have read this year.”
--Books and Movie Reviews (re Any Means Necessary)

In PRIMARY DUTY (The Forging of Luke Stone—Book #6), a ground-breaking action thriller by #1 bestseller Jack Mars, a Supreme Court Justice is taken hostage by a terrorist organization. With a consequential decision before the court, the death of this swing Justice could change the political landscape for decades. 

Getting him back, against the backdrop of a massive marvel of engineering, would be mission impossible—a mission that only elite Delta Force veteran Luke Stone, 29, and the FBI’s Special Response Team, may be crazy enough to take on.

In this action-packed military thriller, filled with shocking twists and turns, the stakes as high as can be, Luke and his team may be up for their most challenging mission yet.

PRIMARY DUTY 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.

“Thriller writing at its best.”
--Midwest Book Review (re Any Means Necessary)

Also available is Jack Mars’ #1 bestselling LUKE STONE THRILLER series (7 books), which begins with Any Means Necessary (Book #1), a free download with over 800 five star reviews!


  • It was great!

    By MisterBatman1937
    It suspenseful, exiting, and nerve-racking. I would definitely recommend
  • Sad Stereotypes

    By OG_AJ
    I, and millions of other Americans, lived through 9/11 and the War on Terror that followed and at no point did “19 conservative states” ban interstate travel by Muslims or North Africans or, anything of the sort. It’s unrealistic, and just a perpetuation of the Stupid, Racist, Fat, Southerner™️ stereotype that, in an era of ultimate political correctness, is still the only racist trope allowed in media. Mars has been very enjoyable to read, but the gradual deification of ultra-liberal Dixon as President, Ed Newsome’s increasing racialization and now this ham-handed storyline have reduced his work to yet more woke nonsense. Seems the wrong genre to sell lefty SJW fantasies, but there you have it.
  • You can do better

    By Eric real name. Waste of $
    Jack Mars is great author and had to know this was not very good work.
  • Can’t put it down Action

    By as477562910
    This is a great challenge for Luke Stone. Jack Mars paints a real life picture that makes the reader feel like they are right in the action. I could not put the book down. I felt like I had to keep reading to make sure the potential victims stayed safe.
  • Action as usual

    By hatchypapa
    Another non stop action adventure from Jack Mars. For this one, a reader would benefit from having read earlier books to be clued into references to the past. I rate it “okay plus”.

    I been waiting for this book of the continuing adventures of Luke Stone, the action pack of this book as the other books in the Luke Stone series kept me interested and wanting to read more. Jack Mars has not disappointed me yet. Kevin
  • Explosive!

    By Zoe Aionios
    The first 9 chapters set the stage then Primary Duty becomes another fast-paced, action-packed thriller that you can’t put down!! Luke & Ed race against time between Germany, Morocco, France and England to thwart a terrorist plot designed to wreak havoc in London. I thoroughly enjoyed this latest installment in The Forging of Luke Stone series!!
