A fine historical read, but very clinical and dry. I honestly didn't care for it, but that doesn't make it a bad book. For what it was, it was fine. For what I wanted it to be, it fell short.

This was not a very well-written book. The narration was terse and juvenile, the characters were mostly weak, and the plot-convenience was frustrating.

The idea was pretty good, but this read like a really poor first draft of what could have been a good novel, if any time had been taken to improve it.

I really doubt I will continue the series.

While it is enjoyable to have new stories in the Ryanverse, this one is mediocre at best. This book has Clancy's characters, but it does not have Clancy's style. It started strong, but weakened throughout as the story went on. Many times I found myself rolling my eyes at the dialogue, descriptions, and characters.

The Jack Ryan in this book is not the Jack Ryan from Red October (which took place shortly before this story) and the Mary Pat Foley is not the Mary Pat Foley from Red Rabbit or Cardinal of the Kremlin (which took place shortly before Red October and shortly after this story, respectively. They were weaker versions of the characters with different traits and attitudes.

John Clark was maybe the closest character to what we know from the “real” Clancy books, and he was hardly in this one.

The plot was OK, but the descriptions were messy and, many times, I had a hard time following them.

I didn't hate this one. It was better than Teeth of the Tiger, but it failed to completely fill the Clancy void for me. I'll probably read some of the other post-Clancy works, but I won't get my hopes up that anyone will ever be able to replace the man himself.

Corny and predictable, but still fun. There really is something about a train.

Not as good as I remembered from when I read it as a teenager. Amateurish dialogue, ridiculous scenarios. Enjoyable, but overall, meh.

I thought this was a fun, fantastic book that kept me interested throughout.

Campy as hell, but it was fun. An enjoyable, simple read. It takes a stereotypical western and gives it a sci-fi twist with enough corny dialog to make bread.

Corny, but fun. My 13-year-old son loved it.

A cute read.

There is no doubt in my mind, this book was NOT written by Tom Clancy. Poorly written, amateurish dialogue, ridiculous premises. There is no way that Tom Clancy wrote this book. I find it hard to believe that he even approved to having his name placed on the cover, but I guess he must have.

Not as good as the first but worth getting through to the end.

Delightful and fun. I enjoyed this book a lot.

A lot of fun. I enjoyed it greatly.

A little dry and a little all-over-the-place, but a good read with fantastically written dialog. Worthwhile.

I good ending. This one was kind of all over the place and hard to follow in many places, but still worth reading to finish the series.

Ameturish, but fun enough. I few good, creepy moments.

Wow, that was good

It was a good story containing a fair amount of sophomoric dialogue and naive characters. I hear that Sanderson himself does not believe this to he his best work. I will read other parts of his cosmere expectantly and with an open mind.

An enjoyable read.

A pretty good read. Some great stories, but not as technically in-depth as I had hoped. Well written and interesting content.

Wow. That was really good. Great characters, good twists, not predictable. I enjoyed it very much and look forward to the next one.

Wow, what a fun book. Great stories, we'll told. I recommend this book to anyone that loves the game, and likes to read about integrity and honor amongst friends, enemies, and teammates.

Repetitive and repetitive. It also repeats the same themes and themes get repeated repeatedly. I love the characters and the banter, except for how repetetive the banter that I love becomes. This book would have been much better if it had been less repetitive. Now at the risk of repeating myself, I felt this book probably repeated things. I repeat, this book is repetetive.

A fine end to an amazing series.
