“Thriller writing at its best… A gripping story that’s hard to put down.”
–Midwest Book Review, Diane Donovan (re Any Means Necessary)
⭐⭐⭐⭐⭐

From #1 bestselling and USA Today bestselling author Jack Mars, author of the critically acclaimed Luke Stone and Agent Zero series (with over 5,000 five-star reviews), comes an explosive new action-packed espionage series that takes readers on a wild ride across Europe, America, and the world—perfect for fans of Dan Brown, Daniel Silva and Jack Carr.

A devastating lab explosion during carbon dating of newly discovered Dead Sea Scrolls becomes the catalyst for biblical-scale terror as CIA Agent Jacob Snow uncovers a millennia-old conspiracy. Racing against extremist infiltrators who believe the stolen “Seventh Scroll” holds the key to unleashing an ancient weapon of mass destruction, he and archeologist Jana Peters must prevent fanatics from triggering their own twisted version of the apocalypse.

An unputdownable action thriller with heart-pounding suspense and unforeseen twists, TARGET TWENTY-ONE is the twenty-first novel in an exhilarating new series by a #1 bestselling author that will make you fall in love with a brand-new action hero—and keep you turning pages late into the night.
