The Quadrail train connects our galaxy, and takes secret warriors Frank Compton, from Earth, and lovely Bayta, to the horse-like alien Fillies' Proteus Station. The Mohdri, a coral group intelligence, controls minds after a scratch. With the rise of the vicious civilization-consuming Shonkla’raa, is he still their enemy, an ally, or a friend?

My hipster friends turn up their noses at science fiction. They're missing out. Timothy Zahn's stories have enthralled me for years, and Judgment at Proteus is a fitting end to the absurdly enjoyable Quadrail series. I've really grown to like Compton and Bayta, and I'm glad they went out with a bang. That's a bit of a spoiler, but not too much. Enjoy.

What Zahn promised in the first book, Night Train to Rigel, he delivers in Judgement at Proteus. A phenomenal conclusion to a roller-coaster ride of a series.

Fifth and last in the Quadrail / Frank Compton space opera series about Frank Compton and Bayta and their battle to prevent a galactic takeover.

My Take
Frank is so naughty---I love it---he reckons getting Doug and Ty used to table scraps and it not being appreciated is just one more reason to do it.

Zahn is not loathe to spring traps, create setups, and twist things around. I want to go back to the beginning of the series and read it all the way through in one sitting!

More dead bodies. More traps.

"Space opera" on the cover means preceding complicated details, ponderous back story, impossible to spell, pronounce, or remember names, slow momentum to a crawl. Even a chase or fight scene is laid out step by step, good for choreographing a film, not for keeping tension high.

"Fear is a biochemical response that can be controlled or ignored .. hopelessness is a lie and an illusion. There's always hope.. Always" p189. Frank resists the prime method of his enemy's psychological warfare. The appe

This book was a very fitting finale to the entire Quadrail series, with stakes increasing from the enemy faced in the first few books to what seems to be a much more malevolent threat. As always,I enjoyed the main characters which Zahn has developed over the series, particularly Frank and Bayta, of course, as well as the alien races and Quadrail system prevalent in these books.

But, for those of you who are considering whether or not to read this, I should next stop and say: DO NOT READ THIS STA

I really liked the ending a lot. There are future issues, of course, but this thread has definitely reached a pause.

What’s worse than an alien hive-mind entity that plants itself in unsuspecting individuals and wants to rule the galaxy? Try the super-race that designed it and will turn it into a weapon to ensure galactic domination.

Judgment at Proteus is the final instalment in Timothy Zahn’s Quadrail series. The Quadrail is an interstellar train travelling a light-year a minute to connect far-flung solar systems, and Humans are one of the smaller (and newer) groups of life-forms that use it. But it’s a human

Judgment at Proteus is the fifth and final book in Timothy Zahn's Quadrail series. While a complete story in it's own right, it draws on and ties up some many things from previous books it's extremely ill-advised to start here - go back to the beginning if you're new to the series (Night Train to Rigel).

** This review will not contain spoilers for Judgment at Proteus, but will have MAJOR ones for earlier books in the series. **

I have been a Timothy Zahn fan since the first moment I picked up Heir to the Empire, the first of his Star Wars novels. So when I got the chance to read Judgment at Proteus, I was overjoyed. The Quadrail series finale does not disappoint. The Quadrail is an intergalactic train of sorts that connects the twelve civilizations of our galaxy. The story is an amalgamation of spy novel that happens along with a railway murder mystery as told by a Noir detective in a sci-fi setting. That seems like a ...more

Judgement at Proteus (2012) 513 pages by Timothy Zahn.

Fifth book in the Frank Compton/Quadrail series. Fast paced action. Frank gets put into danger time and again pulling himself out of trouble never able to use the same trick twice. He doesn't know who to trust other than Bayta. Especially since his allies can be manipulated to divulge his plans.

In Mighnight Train to Rigel we learn that the Modrhi is a genetically engineered weapon--a microscopic entity that enters a body and then grows and is

Judgment at Proteus is the last in the Quadrail series, tales that span the width and breadth of galaxy.

Frank Compton, a human troubleshooter, is hired by the Chahwyn to escort a young and pregnant earth girl to another world where the inhabitants are masters at genetic manipulation. But this small task is itself fraught with danger and Frank has been secretly assigned to uncover the mystery of the Shonkla-raa, an insidious parasitic species bent on galactic domination. The Shonkla-raa had been

To quote the book cover Judgment at Proteus is “The climactic finale of the epic Quadrail series”. The quote is very true. This is book five in the series and I would not recommend it as a stand-alone. There is a lot of back-story you need to know in each of the books, a lot of history between the characters, and a very dense complex story line that weaves the action together in all of the books.

I think this is Space Opera at its best. Timothy Zahn has written a great story with wonderful charac

Timothy Zahn ends the Quadrail series with a taut, well-delivered story that really picks up the pace of the series. In fact, Books 4 and 5 should really be read back to back as they comprise a single story line with a meaningful plot twist. (Books 1-3 can be read separately.)

I'm not going to review the plot because, by now, you're either a fan of this series or you're not. In either case, what I say matters little.

Only two thoughts to close with:

A satisfying ending to a great scifi series. Zahn had me at "trains in space" and I stayed for the exciting adventures of Compton, Bayta, and other great characters (McMicking!).

At a recent convention Zahn said that the Quadrail series was originally planned for six books but the publisher decided to end it at five. Fortunately this decision was made with enough time for Zahn to wrap up the series. He said the book had some pacing problems because of this, but he was glad to be able to end it ra

Judgement at Proteus by Timothy Zahn

This is the final book of a five book series and I’m not sure it is the best because it is a better book or because it ties up everything so neatly. Frank Compton, galactic troubleshooter is back with his assorted sidekicks from all four previous books. He makes some startling discoveries and has to closely look at his alliances and enemies.

Frank is an engaging character who shows signs of being an somewhat inept James Bond combined with a somewhat more slick

Great conclusion to the Quadrail series. Nicely wraps things up with Frank, Bayta, the Modhri and the Shonkla'raa and ties together things from all the books in the series. Sadly I had forgotten some of the details in the other books but enough was written about them to jog my memory. It did make me want to go back and reread them all now that they're all out without the delay in between the books I experienced.

I love Timothy Zahn and I love how he writes mysteries with the characters always knowing more than the reader and twists aplenty. Generally they're quite well done and each is unique. I thought this was a great series overall and this book generally brought it to a conclusion. I thought some of the ending twists were a little strained and would have enjoyed an epilogue. For the series as a whole, sometimes it was well-paced, sometimes things dragged a bit, more than usual in Timothy Zahn.

I suppose a book has to be given five stars in certain circumstances. Such as when your husband gets up a 4am, and instead of sensibly going back to sleep, you turn the light on and pick up the book because there are only 60 pages left. Or when you are so close to finishing that you carry on reading and are subsequently late for work, even though you work from home and your commute takes about five seconds, and technically nobody could see if you were sat at your desk reading (I would never even ...more

Great finale to the series. This series moves away from the confined spaces and limited passengers of earlier novels to large scale confrontations, jetting investigator Frank Compton and his companion Beyta from space stations to planet surfaces, collecting the varied allies -- and enemies -- that he's encountered, in one fairly explosive final confrontation. As befits a SF detective novel, filled with (perhaps somewhat anachronistic) references to classic noir films of the 20th century, everybo ...more

A good conclusion to the "space train" series, as I call it. It starts out a little slow as the first half of the book takes place completely on a space station; no space trains. Still the mystery there is interesting and it has some great moments, especially the climatic confrontation.

From there they race across the galaxy trying to stop the great conspiracy. There are some revelations that are treated as huge, but ultimately I felt were a little over dramatic and Bayta seemed to be more in the

Timothy Zahn brings his five-part Quadrail saga into the last stop on the line. His characters are fallible but smart, his pacing is excellent, and he consistently manages to hook me in pretty short order.

Not everything always goes as main character Frank Compton plans, but he manages to "live to tell the tale."

If you haven't read anything by Timothy Zahn, you're just plan missing out. He consistently makes me wonder, "What's gonna happen next?", and always delivers a satisfying read.

Rousing possible finish to the "Quadrail" series? Space opera at it's finest. Zahn really outdoes himself, in this 4th book of the series. Great pace, characters, and a twisting plot, with a fairly serious wrap up of the major threat to the universe. Super Agent Frank Compton, and his partner Bayta, are relieved of their duties to the "Spiders", and are headed to Earth, at the end. Happy to be together, and seeking employment. Is this it for our intrepid heroes? I get that distinct impression, a ...more
Last book in a series I read for the Endeavour Award. I might actually like this series more if I read it from the beginning and not just the last two books. A galaxy wide hidden conflict between an interlocking set of psychic aliens with the humans to the rescue kind of. But some of the conceits I found bothersome - all the explaining - clearly outside the advice of the Evil Overlord List. The side references to human historical movies (especially Casablanca), whatever. Still, the ideas were go ...more

Conclusion of space-train-thriller series with mind-control aliens and politics and plots and betrayals and -- ooh, everything. I've been hoping the author wasn't going to string out the story too far, and maybe it could have been three books instead of five, but no complaints; this is a satisfying finale. Unless you think too hard about all the tech constraints that are supposed to make the plot make sense. Don't do that.
Victoria Gaile
This is not his best series, but it's a reasonably entertaining read. It's not the sort of book where the reader can figure out what's going on ahead of time, because the main character never tells everything he knows. But at least, there is an in-plot reason for that to be the case, what with telepathic group minds and unknowing alien spies and all. I enjoy seeing what he came up with this time as the secret plans unfold.
Jun 28, 2012 Jim rated it liked it  ·  review of another edition
This is the fifth, and final, book of the series. I've noted through the years that he writes well, but doesn't always finish strong. It is still an enjoyable book (I give most books three stars unless they force me to go up or down from three). My biggest complaint is the hero's dialog seemed to be the same in every scene, and there was a lot of dialog. I still recommend the series (including this book).

The rate at which I read a book is usually a good indicator for me of how much I am enjoying the story. I am loving this series. Again, it is great that Bayta has more of a primary character role and their relationship is a great additional aspect. The role of the Mohdri has also changed and it is a great plot twist.

This is the last book in the "Quadrail" series that started with "Night Train to Rigel". I must say the entire series has been a real train ride, pun intended! I am sad to see the series end but as an ending this book could not have been better. I hope Mr. Zahn sees fit to bring back Frank Compton and Bayta in further adventures.

Excellent series, super fun and remains light throughout.

The finale does not live up to the other books in the series. That said, I still rate it an outstanding 5 based on the fact that the entire series is a good read and that this dos tie up the story well.

Fine ending to a great series. I really liked the two heroes all the way through, and it was good to see them trusting the other's judgment numerous times in this book. Climax seemed a little rushed to me.
