“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 conquistador’s recovered diary becomes the roadmap to immortality when Jacob and Jana discover it reveals the alleged location of the legendary Fountain of Youth. Racing against a ruthless tyrant who seeks eternal life to cement his reign of terror, they must reach the mythical fountain first—but some legends are more dangerous than the monsters who hunt them.

An unputdownable action thriller with heart-pounding suspense and unforeseen twists, TARGET TWENTY-FOUR is the twenty-fourth 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.

Future books in the series are now available!
