GHOST CHAIN (Book #4) is the fourth book in an exhilarating new thriller series that blends mystery and action, from the #1 bestselling and USA Today bestselling author Jack Mars (with over 10,000 five-star reviews). The series begins with GHOST UNIT (Book #1).

When the FBI creates an elite team to investigate murder mysteries in military hotspots, there is only one man for the job: retiring Marine sniper Cyrus Drake. Partnered with brilliant FBI Agent Phoebe Colt, Drake must complement her investigative genius with his tactical skills—and together, they will solve mysteries and hunt down killers in the world’s most dangerous and action-packed places.

In GHOST CHAIN (Book #4), when a retired Marine intelligence officer is found dead in a Moroccan hotel room, the cause of death looks natural — but Phoebe Colt knows better. The trail leads into the lawless corridor between Mali and Libya, where a deadly arms broker has been flooding jihadist factions with stolen weapons, and the clock is ticking to find a hidden cache before it vanishes into a dozen different warzones.

The Cyrus Drake combines the best of a murder mystery series with the best of a military action thriller, delivering relentless action and sharp tension from the first shot fired to the final, stunning reveal. It is a series that won’t allow you to catch your breath until the last page. Perfect for fans of Brad Thor, Lee Child, and James Patterson.

Future books in the series are also available!
