Ghost Unit
“Thriller writing at its best.”
--Midwest Book Review (Any Means Necessary)
⭐⭐⭐⭐⭐
GHOST UNIT (Book #1) is the first 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).
When the FBI creates an elite team to investigate murder mysteries in military hotspots, there is only one man for the 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 UNIT (Book #1), when a Navy SEAL is found dead in a Manila alley with no mission on record, Drake and Phoebe are pulled into a city where the line between hero and victim is razor thin. What looks like a sordid secret quickly explodes into something far more dangerous — and bringing the killer to justice means taking on an entire syndicate that doesn't leave witnesses.
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!
“Thriller enthusiasts who relish the precise execution of an international thriller, but who seek the psychological depth and believability of a protagonist who simultaneously fields professional and personal life challenges, will find this a gripping story that's hard to put down.”

“One of the best thrillers I have read this year. The plot is intelligent and will keep you hooked from the beginning. The author did a superb job creating a set of characters who are fully developed and very much enjoyable. I can hardly wait for the sequel.”

**Ghost Unit by Jack Mars**
*Ghost Unit* delivers an exciting combination of military action, investigative suspense, and international crime that makes for a compelling start to a new thriller series. Jack Mars builds the story around an intriguing partnership between two professionals with very different strengths: retired Marine sniper Cyrus Drake and brilliant FBI Agent Phoebe Colt. Their assignment brings together tactical experience and investigative intelligence, creating an engaging foundation for a crime thriller with plenty of action.
The Manila setting adds an especially dangerous atmosphere to the mystery. When a Navy SEAL is discovered dead in an alley with no official mission on record, Drake and Phoebe are drawn into a case that quickly grows beyond an ordinary murder investigation. What initially appears to involve a hidden personal secret develops into a confrontation with a powerful syndicate, raising the stakes and making the pursuit of justice increasingly perilous.
One of the strongest elements of the premise is the contrast between Drake and Phoebe. Their complementary abilities give the investigation an interesting dynamic, while the military background and international setting create opportunities for both strategic problem-solving and high-intensity action. The story also explores the difficult territory between heroism, secrecy, and accountability, particularly when the victim's circumstances raise questions about what really happened.
I especially like the concept behind the series: an elite FBI unit investigating murders connected to military hotspots. It creates room for mysteries that are not confined to conventional crime scenes, while allowing each case to explore different environments and dangerous networks. The blend of a murder investigation with a military action thriller should appeal to readers who enjoy fast-moving plots, capable protagonists, international intrigue, and escalating danger.
Overall, *Ghost Unit* sounds like an entertaining and action-packed introduction to the Cyrus Drake series. Readers who enjoy military thrillers, FBI investigations, and suspenseful international crime stories will find plenty to interest them in this first installment.

Fast read
Great storyline. Well thought out characters and the story was reasonably paced. Didn’t lose interest at all, as a matter of fact I lost track of time not wanting to put it down.

a rip roaring adventure tale
A gripping tale of an ex military guy who can’t do retirement…. So finds himself battling bad guys in Manila to free a group of trafficked women. A fun romp and there’s apparently more adventure ahead in the series!

Clandestine action everywhere
Lots of intrigue and action. A little slow paced in the beginning but rose to a satisfying crescendo in in the final chapters.

I thought that this was a pretty good read. Started strongly before settling to more standard fare. Reasonable pace and entertaining.

It was a decent read, but at times felt like it got a bit fanciful. Cyrus is nearly too good to be true in how he can take down heavily armored men with only a few problems.
Phoebe figures out, sometimes, you do need to skirt the law...even in another country.
