Un avance sorprendente de la física cuántica ha hecho pedazos las fronteras entre los universos paralelos y la historia se convierte en un caos en que diversos mundos alternativos entran en colisión.

I haven’t read any Frederik Pohl, which is a little embarrassing as he won several Nebulas, a Hugo, and the National Book Award. SFWA named him as their 12th Grand Master and placed him in the Science Fiction and Fantasy Hall of Fame in 1998. He passed away in 2013.
I’m not sure “The Coming of the Quantum Cats” was the best choice as my first Pohl novel. I chose it because it was standalone, explored parallel worlds theory and I thought it would be a quick read. While there is certainly some value and enjoyment to take from this novel, I ultimately found it to be a clunky, slow read that didn’t age well.
Let’s start with what I liked. It was fun to see Pohl explore other possible worlds with both big and small implications. While there are an infinite number of parallel worlds, we largely get to explore four or five. In one, there is a fascist America with religious persecution controlled by distant rich Arab power brokers. In another, another Nancy Regan is president, governing a highly militaristic society. The politics seem cynically exaggerated. In some worlds, technology is far behind while others are more advanced. Pohl explores multiple versions of the same characters and shows how they can become totally different people with unique politics and morals due to their environment. I also like the continuously change in direction of the plot, because frankly, some of the plot lines were getting boring. It’s the big implications of parallel worlds that is the strongest part of this book.
So what was my issues with it? Well, the book jumps around to different parallel worlds – that’s not a major issue, but then it also changes character perspective every chapter. It wasn’t that I couldn’t follow the plot, but I just found it jarring and awkward. Anytime I was drawn into a character or plotline, we skipped off somewhere else. I also found the work to be dated – not Pohl’s fault, but to me the culture references came across as antiquated instead of nostalgic. In the end, I never really cared for the characters and the ultimate plotline was underwhelming and pessimistic. It wasn’t exactly groundbreaking either, with H.G. Well’s “Men Like Gods” in 1923, Phillip K. Dick’s “The Man in the High Castle” in 1962, and David Gerrold’s “The Man Who Folded Himself” in 1973, among many others.
I’m not giving up on Pohl’s work based on the accolades and recommendations of many others. However, I’m rating this novel three stars as an interesting, but dated and poorly executed exploration of the discovery of parallel world travel in the 1980’s. ( )

Tight science fiction, fast-paced. Lean, very little fat.

The author begins by telling you the story of a man in a world that subtly isn't our own, and it is enjoyable to realize that concept as little details are dripped out to you.

The 'concept' driving the store is dealt you you really enjoyably as well, and while I don't know science, I thought it was used effectively.

The characters, in 'classic' scifi tradition, are rather thin. You won't find much there to identify with or enjoy. There's a film-noire thinness to them, but it's embedded in so much machismo that our world as probably moved on from it being something that doesn't grate.

There are weird hints of recognitions that this isn't a world of straight white manly men, but they're played off in a way which I can't tell if its for laughs, in mockery, or understanding them to be valid while sneaking them into a readership that is probably hostile to them.

It's a quick read, and even if you don't like the content, it's worth appreciating its style and form for what it is. Also the concept and what Pohl does with the concept is worth some thought and musing. ( )

The problem with having written as many great works of science fiction as Frederick Pohl has is that sometimes that opus can overshadow a title or two. While not entirely neglected, this novel is usually not ranked alongside such classics as The Space Merchants, Gateway, and Jem. Perhaps it does not measure up to these works, but it is nonetheless an enormously enjoyable book.

Set in the then-contemporary world of 1983, the novel follows the different incarnations of three characters – Dominic DeSota, Nyla Christophe, and Larry Douglas – as they deal with their counterparts from alternate worlds. Pohl uses the premise to posit some very different Americas, but the real focus is on the very different people these characters became within these worlds – one Dominic is a senator, for example, while another is a meek mortgage broker and a third a major commanding an assault force. These characters confront each other as their different timelines clash – and face the increasing danger posed by the unintended consequences of travel between their worlds.

The greatest strength of the book is not in the alternate worlds Pohl describes (many of which are satirical takes on the America of his day) or in his use of historical personages, but in the characters he creates. Though his premise is based on developing different permutations of just a few individuals, he nonetheless makes each of them distinct and interesting. Through them the reader is offered an interesting mediation on how different circumstances can shape character – all within the context of a novel that ranks with the best works of alternate history.

An fairly short parallel universe novel. It reads as if it is older than the published date, 1986, more like a 50's or 60's novel. That may be deliberate, as several of the universes portrayed are behind ours in technology, but it still feels like 'old' science fiction. Interesting, but not great. ( )
