At one time, Ursula Le Guin posited a story where a man would fall asleep and the world would change every time he dreamed. He didn't like that. He tried to avoid dreaming until an evil psychiatrist started controlling his dreams. The point is the world changed every time he slept. For Dr. Who and his amazing TARDIS, the universe changed every time he closed the callbox door and you never knew where he would end up except you knew he would be chased by Daleks. In other stories, people race throu ...more

"Here’s the situation. Every time I fall asleep, I wake up in another universe. That started happening nearly three years and a thousand worlds ago, and I still don’t know why, or what happens during the transition, while I’m asleep."

It is never really explained how Zaxony (or Zax) Delatree got this dimensional drifting affliction (although there is a strong implication). Zax has been keeping a diary about his adventures, and that is what you, dear reader, are perusing.

It is possible for Zax to

This was an interesting exploration of multiverse theory told in a close and often intimate perspective. I want to describe this as a sci fi thriller, but in reality the narrative is much slower than the pager turners normally given that label. Certainly it still held my attention but there was not a lot of action in the story. Instead it was more focus on the characters. Towards the second half the story picked up with some interesting narrative shifts, however it fully immersed me.

An interesting concept for sure but the concept is more interesting than the story itself.

The story of Zaxony Delatree and his journals explaining his extraordinary life of travel to many many worlds. Existing in a multiverse, when Zax falls asleep he wakes up in another world in an alternative universe. Along the way he meets up with various characters, bringing some with him. They also have to be asleep and hanging on to him to travel with him.

One of these characters has ulterior motives tho

Review first published on The Curious SFF Reader

Zax Delatree has a special ability, every time he falls asleep, he travels to a new random dimension. Sometimes, he wakes up in dystopian world and sometimes he wakes up in a fantastical world where evil mushrooms try to kill him.

If Zax falls asleep holding someone in his arms, he can transport them with him. A lesson he has learnt the hard way the first time he traveled to a new reality. However, most of Zax’s companions tend to abandon him after

Thank you so much to Angry Robot Books for the digital advanced copy of Doors of Sleep in exchange for an honest review! All opinions are my own!  If you are a fan of multiverse adventures and creative characters, check this out!

Wow, what a wild ride! I can only imagine how Zax feels since I was getting dizzy just travelling with him!  I think the book's biggest strength is just the sheer number of creative ideas on the pages - I coined a term for it, like "word salad" but it's "universe salad."

The nitty-gritty: Inventive and engaging, Doors of Sleep is the feel-good sci-fi story you didn’t know you needed.

If you’re looking for an upbeat, quirky, feel good story to start off 2021, then you cannot go wrong with Doors of Sleep. This book was such a happy surprise, and I can’t believe this is my first time reading Tim Pratt! With an almost retro sci-fi vibe, Pratt has managed to write an entertaining story with loveable characters, a thrilling plot, some timely social commentary, and plen

4.5- This was just the type of escapist read my wild imagination needed! This story is written in journal entry form about the circumstances that found the main character Zax to be traveling through multiverses every time he fell asleep. Fall asleep- wake up in a new world, fall asleep-new world and on and on. Oh, how many worlds he visited! Some were the strangest type of places you could not even imagine and some were seemingly normal. Along the way he acquires several companions that travel w ...more

Some time ago, I read quite a bad book with a main character named something similar to Zax, which is what this book's main character is called by his friends. Not only that, but the author's first name was not too dissimilar to Zaxony. And the premise was that whenever the protagonist fell asleep, he shifted into another universe.

So I wondered, when I picked this one up (having been fortunate enough to be invited to review it by the publisher, via Netgalley), whether it was prompted by the aut

For the amount of portal fantasy/sci-fi anime (isekai) that I watch, it is something that I rarely delve into in fiction, so the Doors of Sleep was an interesting venture into the unknown for me, and what an adventure it was. Overall, I had some mixed feelings about this book, but one thing that I can say with certainty that I loved was the portal aspect and getting to see new worlds – and so many of them. I can only have the deepest admiration of Pratt for being able to come up with the concep ...more

Every time Zaxony Delatree (Zax) falls asleep, he travels to a new reality. He has no control over his bearing and never revisits the same place twice, making his life a constant, spontaneous adventure. One that he can neither stop nor control. Sometimes he’ll wake in paradise, with plenty of food and a no worries beyond his next nap. Others he’ll wake in hell; worlds of brimstone or desert or glass, worlds at war or apocalypse, worlds filled with m

Well, another strange one.
This time we follow the adventures of one Zaxony Delatree, Zax to his friends and enemies. After witnessing an attempted suicide, Zax develops the ability to travel the worlds (planets or parallel universes, not sure) as soon as he falls asleep. He can't really control his power, which is a problem. He meets and interacts with the inhabitants of each world he visits. He also realizes that he can take other people with him,

REVIEW: I thoroughly enjoyed this entertaining portal adventure, which has a pleasingly old-fashioned feel. The overarching narrative is very straightforward. For reasons that poor Zaxony doesn’t fully understand, every time he falls asleep or unconscious – he jumps worlds. Initially, he spends his time in a horrified daze as he tries to come to terms with his new normal. For the worlds that Zax encounters are mind-bogglingly various, ranging from idyllic to nightmarish and everything in between ...more

An interesting concept but a rather lackluster execution. Zax is not a very active force in his own life, relying on companions to give his life meaning and direction, even though his whole shtick is that every time he sleeps he ends up in another world. Every problem he encounters is solved within pages and there doesn't seem to be an overarching goal in the story. Certainly he would like to go home or at least be somewhere consistent, but he's not actively fighting for it; instead he

Doors of Sleep follows Zax Delatree through many worlds, each time he falls asleep he awakens in a new world. Constantly travelling, meeting friends and making enemies along the way, as he tries to leave a little bit of himself and make each world a better place when he can.

I went in to Doors of Sleep a little blind, just knowing it involved Zax travelling. What I didn’t expect was such a beautiful story of friendship, splashed across dozens, hundreds of different worlds. Told through journal e

Every time Zaxony Delatree falls asleep, he wakes up in another universe, with very few similarities between them, except for perhaps a humanoid biosphere followed by a land of trees birthed with deadly creatures, or a technocratic societal world in the desert followed by one that’s airborne. There’s really no telling the distance of space-time between them, and any world is possible.

The possible existence of a multiverse, an infinite string of worlds in which life is the same, but very much not too, in its expression, is, for many people, an entirely alluring idea.

To think that out there somewhere exist endless possibilities for life, a great many of which bear no resemblance to our own reality, is appealing in a world where everything seems perpetually, drably the same.

I received this book as an ARC for an honest review from Netgalley. I have very mixed feelings about this book. On the one hand, I loved the concept of its multiverse and found it a very creative backdrop for a space opera; on the other hand, it felt as if the author had come up with an amazing setting and strong hook, and realized he needed some conflict, so he added a stereotypical super-villain to the mix.

This is the story of Zaxony Delatree, a man with an unusual medical condition that enab

I freely admit to having a bit of a mixed experience with this author in the past - I really like the Marla Mason books but bounced quite hard off the previous sci fi novel of his that I tried, so this was always going to be a bit of a gamble...

The basic premise of Doors of Sleep is that our protagonist has discovered that when he falls asleep, he moves to a different universe - by the time we meet Zax, he has already travelled to hundreds of different universes, gaining and losing companions al

Such a wild and unexpected ride! A unique spin on multiverse journeys that suck you into the different worlds and leave you wanting more. This was like Dr. Who meets a dreaming world jump matrix. Possibly even a slight vibe of A Wrinkle in Time could be debatable.

I found the character depth to be part of my favorite aspects of this read. I connected with Zax a lot. Especially with his loneliness before Minna comes into his life. He is a strong character with relatable flaws and a good heart. Th

There are times I wish I could to other universes just to run from this one. I think most people feels this way sometimes.

Zax is someone who actually can. He didn't choose this but he has no choice. Every time he falls asleep he travels to another universe. He can prolong his stay with stimulants but eventually he falls asleep. But he can take people and stuff with him if he hold the person in his arms. The person he holds must be unconscious because if not, it has consequences, the person goes

For reasons that are never explained, Zax developed a problem. Every time he goes to sleep, he wakes up in a different universe. It’s a one-way trip, and he seems to have no control over where he goes. Something ensures that he wakes somewhere he can actually survive, at least in the short term: not inside a wall, or under miles of water, or in the vacuum of space. However, longer-term survival (meaning the next half hour sometimes) is definitely NOT guaranteed. He’s been living like this for ye ...more

"Doors of Sleep: Journals of Zaxony Delatree" by Hugo award winning author Tim Pratt is an adventurous tale of what might happen if an ordinary person suddenly develops the ability (or perhaps the handicap?) of mysteriously shifting into an alternate reality each time they fall asleep.

As soon I started this book, I sighed. "Oh great. Another multiverse novel. Just what I needed." And in truth, it took a few chapters before Zax grew on me enough to really get into the book. He's sort of an Arthur Dent (Hitchhiker's Guide) character stuck in a multi-verse version of Gulliver's travels. Every time he falls asleep, he jumps between universes, never knowing where he'll wake up.

This is, of course, handy for the author, because he gets to write about a whole new world every time Za

"Here's the situation. Every time I fall asleep, I wake up in another universe." Twenty-two-year-old Zax hurtles through a complex multiverse in Tim Pratt's Doors of Sleep: Journals of Zaxony Delatree. This imaginative adventure stands on the shoulders of classic science fiction action novels like H.G. Wells's The Time Machine and provides as much entertainment.

This is a great sci fi story, really imaginative, with some great lessons thrown in. Admittedly, one of the major lessons is "If you're hurtling helplessly through the multiverse, find a created plant person to bring along because she'll be really useful" but who knows when we'll need to know that!

I loved the varied civilisations Zax meets on his travels: some real thought has gone into them, even the ones that we skip past very quickly. These aren't cookie cutter planets, they're distinct and i
