Considering it's a Star Trek novel, Entropy Effect is by no means a bad book. I can't, in good conscience call it a particularly good book. It was like an oatmeal cookie. A quick snack. I probably would have preferred chocolate chip, but I was all out and, besides, I knew what I was getting when I reached for the oatmeal cookie and - I'm just making myself hungry at this point, so I'm going to drop the analogy.

Bottom line: It's short and decent, but I've read superior fanfiction online and for f

A little break from all these picture books seems to be in order, so let's go with something completely different: The Entropy Effect by Vonda N. McIntyre, which is #2 in the Pocket Books line of Star Trek novels.


The Enterprise has been in orbit of a singularity for six weeks, Mr. Spock making careful observations of this unusual phenomenon, when they are called away to Aleph Prime by an ultimate override command--to be used only in the most dire of situations.

They arrive to find no great eme

For a tiny little book it sure packs a heck of wallop! It's a little slow to get going but once it hits its stride (by that I mean the events described in the summary come into play) it is ridiculous and very close to being nail biting.

Everything is weird from the word go. Spock and Kirk are weird with each other - I don't know where in the chronology this novel fits but I'm betting early days since both of them aren't quite as Best Friends Forever-y as they end up being yet - but it's not just

The Entropy Effect was a diverting read that improved after a somewhat rocky beginning. By the end of the novel, original characters felt well-fleshed out, even if they didn't necessarily feel like they would have been a part of the original Enterprise crew. I enjoyed the way time-travel was handled in this book, even compared to how the original series handled it. There are consequences to all temporal actions, even beyond the mere rethreading of human history. For those who are interested in e ...more

Read the whole thing in one day sitting by the water. Whenever I put it down to get some Diet Coke or take a bathroom break, I spent the whole time wondering what would happen next. That's my idea of perfect vacation reading.

When it was originally published in the summer of 1981 Vonda McIntyre's book represented something of a new frontier (if you'll forgive my use of the phrase) in the Star Trek franchise. Though the second entry in Pocket Books's series of Star Trek novels, it was the first original story they published (the first book was the novelization of Star Trek: The Motion Picture ). As such, it represented an effort to develop the franchise, rather than the more half-hearted adaptations of the Bantam Boo ...more

I wasn’t really excited about one more StarTrek the me travel story and about 2/3rds through, it seemed like it was going to be the same as most time travel stories. The end, however, is a bit unique. I will admit that I enjoyed this old TOS based story.

First, I'll just say that the 1981 edition with Mustache Sulu is superior to the "Let's pretend this isn't Spock mindmelding with a Horta" cover from 2006. Which is terrifically distracting if you know the context. Second, I'll say that this first unique paracanonical novel in the Star Trek Pocket Books series as an example of its genre totally earns the 4 stars I've awarded it. This was a great pick for the first in the series following the novelization of Star Trek: The Motion Picture. McIntyr ...more

A generic sci-fi time travel story, Star Trek: The Entropy Effect is a weak and uninspired novel. While studying a spatial anomaly the Enterprise receives a priority distress call to transfer a dangerous criminal, but when the criminal turns out to be a well-respected scientist Spock begins to suspect that there’s more going on than they’ve been led to believe. It’s a pretty simple, formulaic story that telegraphs its every move. Additionally, some of the crew members are written out of characte ...more

This was an absolutely epic novel of the Star Trek franchise. As a Spock fan (as too many of us to count are), this is a perfect novel to make my heart sing. I am also a fan of temporal science fiction, so as Spock fights the entropy effect to restore temporal stability in the universe, I hung on every word. An excellent novel, interesting story, and chalk full of Spock, what more could you want?

This is a book that I read quite some time ago and I’d remembered thoroughly enjoying it. Would it still have the magic? Oh, yes.

Vonda McIntyre was my favorite “Star Trek Universe” writer. Her characters grew beautifully from the series, spreading out in ways that we as viewers hadn’t seen before, but that didn’t betray what we already knew about them. There was also a comfortable expansion of science so that it felt futuristic. I learned quite a bit about “entropy.” It was a new adventure of a

When I read a Star Trek novel, I weigh it not in terms of other fiction but as a new episode of Star Trek.

The Entropy Effect was the first Trek novel published after the novelization of Star Trek: The Motion Picture. Although the original cover had the uniforms from the first Trek movie, the novel is obviously set during the Enterprise’s five-year mission.

For some odd reason a note is made that Sulu is growing a moustache and long hair. I guess so that he has that cool 1970’s look. The story doe

I loved this book starting out. The characters were spot-on, the friendship between Kirk and his past love Hunter was natural and warm, and the Security Officer Mandala was awesome. For that reason, it gets three stars.

The plot was not great. There’s a lot of overly secretive secret-keeping, and Mordreaux is childishly protective of his “friends” that he sent to the past. The way he talks about it you think there must have been some conspiracy or something, but it turns out they just thought li
I pulled Vonda N. McIntyre’s The Entropy Effect from my Star Trek shelf. I’ve read it several times but not recently. I’m sure when I first read when I was thirteen, I loved it. Kirk, Spock, Dr. McCoy—the whole gang is there so how could it disappoint? It’s certainly not as entertaining to read now but it’s not a bad book to have in your Star Trek collection.

The Enterprise has been assigned to study a singularity that had mysteriously popped into existence and the whole crew is on edge, balance

Vonda McIntyre tells an authentic and rousing Star Trek story with her oldie-but-goodie novel The Entropy Effect. This was the first non-movie Star Trek novel published by Pocket Books. It fit into the theorized second five-year mission that most of the early Pocket books did (similar to the ST animated series).
Like many Star Trek outings Kirk, Spock, and McCoy are main characters. Mr. Sulu also gets a lot of story time. Mandala Flynn, a new ship's security chief, provides another lead character

Classic Alternate Timeline story where Kirk is killed by a future version of a mad professor – who was also Spock’s mentor (ofc) – and Spock trying to rectify it for the good of the universe (no seriously if he doesn't the universe collapses in a hundred years.

It's tried and true trek storytelling done to death since death. I liked it, although the two main antagonists - the Mad Scientist and the Overzealous attorney are very cartoonish.

Some notes I had:

- Georges Mordeaux is such a late 70s earl

Es la primer novela de Star Trek que leo, a la vez la primera de la recién fallecida Vonda N. McIntyre, una escritora prolífica de ciencia ficción. La novela me encantó, no solamente por estar basada en una de mis series favoritas de ciencia ficción; sino también por retomar la esencia de la misma e imprimirle su sello (creo que Vonda se convertirá en una de mis escritoras preferidas). Me gusta como lleva a Spock al límite y lo quiebra de tal forma que lo muestra más humano. Me gusta como detall ...more

I read this book many years ago when it was first released and all I could remember was that I liked it. I recently moved some books around in my home library and saw it. The book silently called out to me saying, "Hello Old Friend! Remember me? I bet you don't - only that you enjoyed reading me. Why not read me again?"

Well, I did and I am very glad.

Thankfully, The Entropy Effect was a strong start to Pocket Books' original novel line. It is a fun adventure featuring some fascinating twists and turns for our heroes, putting them in situations that hadn't been seen in Star Trek up to that point. There was a great deal riding on the shoulders of this novel, and Vonda McIntyre delivered a strong story that served to flesh out the world of Star Trek in new and interesting ways.

Crítica publicada originalmente en mi blog.


Durante días, el U.S.S. Enterprise se ha dedicado al estudio de una singularidad en el espacio-tiempo, un fenómeno de vacío que tiene perplejo incluso al vulcaniano oficial científico de la nave, el Sr. Spock. Por alguna extraña razón, la entropía en el entorno ha aumentado aceleradamente, y ello podía tener consecuencias desastrosas para el futuro del Universo.

El estudio del fenómeno se ve interrumpido cuando reciben un mensaje de emergencia

I really enjoyed this book. I found this both in kindle edition and audiobook at my library. I'm so happy I checked out both. I started to read the book and at night put in the audiobook before I went to bed. Amazing! I had no idea that George Takei and Leonard Nimoy narrated it. I ended up listening to the entire book in one sitting. I highly recommend the audiobook. Takei did an assortment of character voices and Nimoy read only Spock dialog and thoughts. It was a fun time travel style adventu ...more
