I was so interested in Echo of Worlds as the next book in the Pandominion Duology, however, this second book fell a little flat for me. The premise for this duology was exceedingly interesting and the idea of the characters and their missions had such great promise. I do, however, believe the author fell into an info-dumping trap that can happen easily in the Sci-Fi genre.

I was able to give the first book a pass for the overwhelming amount of information with very little plot because I believed it was being set up for the second book, but that was not the case. I still finished Echo of Worlds without caring about any of the characters because of the incredibly weak character building in this story. There were some great scientific theories explored throughout the duology, but to me, the way they were presented was more like a college lecture than reading the epic story it was meant to be.

An intricate, brilliant, and thoroughly mind-bending conclusion to Carey's multiverse duology. I love the vast scope and propulsive energy of this book, and the way it manages to weave profound emotional connections (and adrenaline-pumping action scenes) into a story that, at times, seems to almost fly off the handle into some seriously dense, hard scifi territory. While the multiverse and the science powering it are at the heart of the plot, it is the characters that make it work for me. The bonds between them, both of friendship and sharp conflict, is what gives the story the heart and soul it needs. Also, Carey's choice of narrator for this duology is inspired.

This was such a strong conclusion to this series, it had everything that I was expecting in the scifi genre, M. R. Carey has a strong way of telling the story and thought the overall concept worked. I enjoyed getting to know the characters and how they continued in this story.

Echo of Worlds is a satisfying conclusion to the duology which began with Infinity Gate. The five main characters begin looking for a way to end the battle between the Pandominion and the machine hegemony, which threatens to destroy not just their world, but every world. A complex and fascinating narrative.

The sequel in the Pandominion duology, Echo of Worlds is a VERY satisfying conclusion – but what else do you expect from M.R. Carey, everything this man writes is gold!

Humanity is at risk of extinction in a no-holds-barred war with an AI civilization. The Pandominon – an empire consisting of countless alternate Earths spread throughout the multiverse – is desperately seeking a weapon that can defeat them, consequences be damned. But what if there’s a way to end this conflict peacefully? Are the AI’s really an evil, mindless force? And will the very weapon the Pandominion seeks to use be their own undoing?

We return to the same wonderful characters, a mix of ‘selves’ from different evolutionary chains on different Earths. We have soldiers, AI’s, children, and spies, working together to save their worlds and atone for their own pasts. M.R. Carey seamlessly blends action and a well paced story with the emotional stakes. Thorough world building and character development are a hallmark of this author. I always know when I pick up any of his work, I’m going to drop right into a whole new world where I don’t see gaps or holes in the story. It feels like a world that has always existed and will continue to exist once I put down the book; I’m just here visiting for a bit. The science is futuristic enough to feel exciting and novel, but realistic enough to not feel absurd. The ending feels earned and extremely satisfying.

I’m a sucker for multiverse stories, and if you are as well, then I strongly recommend this duology. It hits all the sweet spots with a complex world, human vs AI, the question of what it is to be human and sentient, rich characters, great science. The first book, Infinity Gate, is just as great, and Echo of Worlds will be out June 25.

Thank you NetGalley and Orbit for an advanced digital copy in exchange for my honest review! This was definitely one of the best sci-fi books I’ve read so far this year.

A wonderful science fiction adventure with an uncommonly hopeful core of empathy. This follow-up to last year's "Infinity Gate" delivers breathless action, terrifc characters, and quite literally mind-blowing high concept sci-fi.

I"m not so sure about Mike Carey but I will follow M. R. Carey until the ends of the earth. I didn't get the musically inclined demon fighter( yes I'm oversimplifying) but the Girl with All the Gifts is probably one the greatest zombie books ever written.
Infinity Gate was amazing and the world building second to none. Echo of Worlds cuts back on the world building and serves up the character development and the action.
If I had to pick between the two books Infinity Gate would be my first choice but Echo of Worlds will high on my list of any sci fi novel. I'm not sure if I was completely sold on the ending but getting there is one of the better reads this year.

I was very interested in the first book of this series which introduced some interesting characters in interesting locations but was a little annoyed that the first book was merely world building and character introduction.

The second book was much worse. After a few side missions, the end of the book was wrapped up in less than 15 pages with tropes that not even the most mediocre writer would attempt. I felt no connection to the plot or the book and I was actually glad I finished the book.

Would not recommend.

[Blurb goes here]

Echo of Worlds is the conclusion to the Pandominion duology, (the first installment was Infinity Gate, 4.16 stars on Goodreads).

Where we left off: the physicist Hadiz Tambuwal is given a second chance at life, if her current state could be called that. She has been working with Rupshe, an AI. Their mission still unknown. Both have been building a team: Essien Nkanika, Moon, Paz and Dulcimer and putting them in every danger imaginable in the process, but that’s nothing compared to what’s coming.

In Echo of Worlds, our characters have escaped death and now are working with Rupshe and Hadiz to solve a bigger than life problem: the war between the machines known as the Hegemony and the organic beings called Pandominion. Both empires have been taking over multiple parallel Earths until they encounter one another. Chances are that the obliteration of the two factions will follow.

Rupshe is bent on sending his team on a wild search: they have to find the strongest being in the multiverse: the Mother Mass. The planet-like entity, with powers surpassing the warring rivals, could be the one being to stop an unimaginable death toll, since both the Hegemony and the Pandominion are creating weapons of mass destruction. According to Rupshe, this deadly event has happened before in the multiverse, it’s called “The Scour”.

M.R. Carey has done it again: he takes you on an action packed journey, one where every player is expendable. One that makes this novel impossible to put down. He complements the story will well-rounded characters, some will redeem themselves, some will perish in ignominy.

Each character has a unique voice and a unique backstory, something very “Carey-esque.” Each member of the team has their own misgivings about the impossible assignment. If they can’t put their differences behind, how can they stop the scour? Even when the AI has calculated every risk and planned for every possible contingency, the reluctant players are not machines, everything that can go wrong could go wrong.

The world building, detailed settings and the unrelenting peril make this story one near impossible to put down.

I loved this duology from start to finish.

Thank you for the advanced copy!

Fitting sequal to Infinity Gate the Pandominion duology. I absolutely loved the premise behind these books. I found the writing smart, imaginative, heavy at points but an exceptionally good Sci-Fi book. M.R. Carey is quickly becoming a favorite author of mine.

Discover the conclusion to the spectacular Pandominion duology - an exhilarating science fiction series from the author of the million-copy bestseller The Girl With All the Gifts . Perfect for fans of The Space Between Worlds, The Long Earth and Children of Time.

Another great installment into another great space opera series. I think the decision to make this a duology rather than the usual trilogy was a great idea, given that everything was pretty much wrapped up in two books and ending very satisfyingly. If you've read and enjoyed other space sci-fi series like Red Rising, Sun Eater, or The Expanse and want more of that type of story, check this one out. A fun 4 star read:)
