Fantastic. Greaney gets better and better. I think this was his best yet.

Thrilling Story. This book is one of Greaney’s best works in The Grey Man series! Action packed and two stories in one with part of the novel relating events from 12 years ago with present day action. Really a fantastic book!

Usual thrills. Page Turner as usual. Did get annoying with the constant switching from present day to 12 years ago! Also need to have Brewer sidelined permanently in a future book!

Great pace going back to the beginning and jumping to present day. Some reviews I read said it was clunky going back and forth but I found it great. Possibly the best Gray Man book yet!

Great Book. Loved every chapter. Was Hard to stop reading!

Greyman. Very good book,like the other books with the greyman

Two books In one!. Book was just ok. Over the top fight and danger scenes but that’s usual in this series. Didn’t particularly like flip flopping from from one story to the other…flashhback stuff.

Sierra Six. Mark Greaney has been waiting to write this book for a long time. Best book i’ve read all summer. Thanks

Best yet. Great series but this is the best of the lot. The duel storylines were handled deftly

Another Great Gray Man experience!. The “two-pronged” story format was excellent. Great to hear of Court’s early days and beginning of Six. Great work, yet again, Mr. Greaney!! Thank you for this series and the hours of reading entertainment.

Best yet. Read them all and this is the best yet. The stories transcend the sometimes awkward writing—usually related to a style that courts screen writing when less explication would perhaps serve better. The secondary characters are more fleshed out with richer backstories than in some previous books. Won’t spoil it but it includes one of the most affecting, even moving, stories of heroism I’ve read. Any fan of the Gray man will be gratified by this one.

Best of the Series!. I’ve read the entire series twice. Sierra Six is awesome at filling in the blanks and setting up even more adventures for Gentry.

Terrible. Worst book in series. Hard to read. Not worth the money. Loved all other books in series.

Sierra six. I paid $14.00 to read 52 pages? This stinks.

Sierra 6. Book has two stories at once Present and 12 years back. Present never finished the hole stories so maybe we see it later. Good book but skipped most of 12 years back Mike M LAS

8.7 of 10. This is one of the best from the Greyman series. Stands well next to Mitch Rapp.

Outstanding. Love the gray series, keep them coming.

I stayed up very late to finish this book. I couldn’t put it down. I like the Gray man.. One of the best of the Gray man series.

Great Read!! Grey Man Still Rocks. Loved the present and post day recounts of the Grey Man!

Sierra Six Review. An amazing story - in fact two stories in one. The back and forth between two storylines was impressive. It was something new and special for the series. I thoroughly enjoyed this.

Double Trouble, Double the Action. Great, great read as usual! Mark Greaney has Court Gentry going back to the beginning to show us how he became Six. In parallel we get the pleasure of a “Present Time” that Court is working through. Action throughout for all!

Sierra Six is a classic page turner.. Best of the Gray Man series, and I’ve read them all. Mark Greaney’s dual (but intertwining) stories spanning 12 years are captivating and act as bookends for the Gray Man’s career.

Gray Man’s Best. I love the Gray Man series. I believe this was the best in the series so far. I couldn’t put it down. A real page turner.

Great! One of the best in series….. Couldn’t put down. Greaney does it again!

Great book. Intense and exciting

HUA. OUTSTANDING

This one I just read.. Cool shades of gray. Just the way Mark likes that Color in between the typed lines. He has away and I'm looking for the next one he writes for the man in Court.

Perhaps the best yet. Amazing read. I’ve read them all and each is a page turner. My wife made me quit reading at 3 am. This may be the best one yet. Mr. Greaney is a generational talent

Read the whole series and loved everyone of them!. This is a great series filled With exciting twists and turns! My only regret is that I have to wait to next year to find out what Violator is up too!

Sierra Six. Best Gray Man book yet.

Sierra six. Wow! That by far is the best Grey man book of the series. The way the author intertwines the two stories, I was on the edge of my seat the whole time. I have always wanted to know the history of Gentry’s relationship with Hightower and how he became Six. This book tied it all together and didn’t disappoint!

Best yet!!. I typically don’t like books that go back and forth from past to present, but this book I think was the best Gray Man Thriller yet. I couldn’t put it down. Bring on the next one Mark!

I waited a long time. Excellent new Grey Man book. Please don’t make me wait as long again!

Way too preoccupied with hardware. Weak attempt at early Gray man character development. The switch between past and present was painfully slow, the resolution lacking believability. Won't be reading another Gray man issue....

Sierra Six. Mark Greaney. Another magnificent read in this series!! A terrorist presumed dead has resurfaced. His primary goal is to remove the Americans from the Middle East by detonating radioactive bombs on military facilities and other key areas. Non stop action. My highest recommendation!

Gray Man. Another great read in this series. Highly recommend.

Sierra Six. Fantastic read.

Powerfully written adventure. There are many of my dozen favorite authors that sometimes write a story that doesn’t really hold your interest cover to cover. I could not stop reading cover to cover and only took breaks to slow down my adrenaline feed. Terrific enjoyment. Have fun.

Sierra Six. We’ll done. An exciting thriller.

Sierra Six. It should have been 2 books, both parts are great, together a bit of a frustrating read

Six. This is one of the best, if not the best, in the series.

I Couldn’t Put It Down. Awesome story. Never boring.

Skip bouncing between two story lines. Tedious and boring alternating between an earlier story line to unnecessarily explain current actions. ‘Suggest you simply skip 12 years ago chapters and only read current actions. Motivation for revenge is clearly cover in single, contemporary story line. If you do that you will find novel interesting and complete, keeping up with escalating suspence and action!
