“You will not sleep until you are finished with AGENT ZERO. The author did a superb job creating a set of characters who are fully developed and very much enjoyable. The description of the action scenes transport us into a reality that is almost like sitting in a movie theater with surround sound and 3D (it would make an incredible Hollywood movie). I can hardly wait for the sequel.”
--Roberto Mattos, Books and Movie Reviews

In this much-anticipated debut of an epic spy thriller series by #1 bestseller Jack Mars, readers are taken on an action thriller across Europe as presumed-CIA operative Kent Steele, hunted by terrorists, by the CIA, and by his own identity, must solve the mystery of who is after him, of the terrorists’ pending target—and of the beautiful woman he keeps seeing in his mind.

Kent Steele, 38, a brilliant professor of European History at Columbia University, lives a quiet life in a New York suburb with his two teenage daughters. All that changes when late one night he gets a knock on his door and is abducted by three terrorists—and finds himself flown across the ocean to be interrogated in a basement in Paris.

They are convinced that Kent is the most lethal spy the CIA has ever known. 

He is convinced they have the wrong man.

Do they?

With a conspiracy around him, adversaries as smart as he is, and an assassin on his tail, the wild game of cat and mouse leads Kent on a perilous road—one that may lead back to Langley—and to a shocking discovery of his own identity.

AGENT ZERO is an espionage thriller that will keep you turning pages late into the night.

Book #2—TARGET ZERO—is also available!

“One of the best thrillers I have read this year.”
--Books and Movie Reviews (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!

    By jley1127
    I've read hundreds of spy thrillers from all the great authors, but this one is a serious stand out. It's similarity to the Jason Bourne story isn't lost on me, but I didn't care at all while reading this. Can't praise it enough, couldn't put it down. So well written and thought out. Can't wait to read the next one.
  • Very good

  • Awesome Spy Thriller

    By Ericd41
    This book was fast paced and a great read! It reminded me of the Jason Bourne movies. I usually don’t write reviews but this one was worth the time. I plan on reading book two in the Agent Zero series. I highly recommend reading this book if you like anything to do with spies, the CIA, action, suspense and a story that is hard to put down at night.

  • Zero complaints, plenty of love

    By Bear-ick mom
    Great premise, masterful characterization, and a quickly twisting plot combine to keep readers turning the pages of this action-packed thriller. With a firm appreciation for true friendship and truer love, Jack Mars gives us a glimpse into a world where the deception one must practice as an undercover CIA agent makes every relationship suspect, even the relationship we have with ourselves. I can’t wait to read the next chapter in Agent Zero’s life.

    Wow. Outstanding in all respects!
  • Tricky and fascinating

    By Skyspy630
    I decided to read the first twenty pages and if I wasn’t hooked, I would discard the book. A few hundred pages later, it was clear that the author knows how to keep you turning the pages. Loved it!
