Summary

It's been years since the Gray Man's first mission, but the trouble's just getting started in the latest entry in the number one New York Times best-selling series.

Before he was the Gray Man, Court Gentry was Sierra Six, the junior member of a CIA action team.

In their first mission, they took out a terrorist leader, at a terrible price. Years have passed. The Gray Man is on a simple mission when he sees a ghost: the long-dead terrorist, but he's remarkably energetic for a dead man.

A decade of time hasn't changed the Gray Man. He isn't one to leave a job unfinished or a blood debt unpaid.

Great story, but...

Another great story that got a little far fetched towards the end. keeping the story believable adds to the enjoyment. Still worth a listen.

probably my favourite series

Cort Gentry likeable and self deprecating, he never ceases to deliver. he's right up there with the likes of McNab's Nick Stone which is praise indeed.

keep 'em coming.

Sierra Six by Mark Greaney

This is yet another brilliant book following Sierra Six the ex CIA assassin but this was different from the other 10 books in the series it covered his early days when he moved from being a CIA assassin to joining Sierra team a group of six men working covertly for America being inserted where their talents were required to modern day. It was cleverly done how it kept switching from 12 years ago to now and how the events of what happened 12 years ago had caused the events that were happening today where as an independent assassin with the Americans wanting him dead for something he didn’t do led to his present situation.

Well read great story

Loved this listen. Very good reader. Story works well. Fills a lot of the back history in about the lead character. I recommend this.

Another great read.

I have always loved the “gray man” series, by Mark Greaney, this book shows he is back on form.
Enjoyed it a lot, and of course well done to the Narrator, a very important job to do well, it can make or break a good audio book.
