Moss'd in Space #1
Moss'd in Space
USA Today Bestselling author Rebecca Thorne delights in a brand new cozy science-fiction romance series...for fans of Martha Wells! Features original inside art!
Torian Razner finally bought a starship, and contrary to Amelia’s assessment, it was not “a meteoric sign of stupidity.” Sure, the alien starship may have been abandoned for a century, and it may be covered in moss now… but it’s Torian’s ticket to freedom, regardless of what her ex… ah, captain… said.
Except Torian’s first flight reveals a surprise the moss is actually an organic computer with a snarky attitude and serious abandonment issues. The target of its loathing? The immortal alien who built it (and then parked the starship, with Moss inside, and forgot about it). The same alien who just found Torian and accused her of “stealing” the ship.
It’s entirely possible that Amelia was right about this meteoric stupidity.

I’m a sucker for talking, sentient plants. Probably because I know that the only way a plant will ever stay alive in my house is if it can keep itself alive. Moss is more than capable of keeping himself alive, which is a good thing since his previous owner ABANDONED him.
Luckily, Torian comes along and is more than willing to be his new best friend.
I love Rebecca Thorne’s work so much. She writes such amazing, heartfelt characters that are so realistic in their feelings and attitudes. I am always here for a snappy comeback whether it’s from an orc, a human, or a plant. And I’ll be here impatiently waiting for the next book in the series.
Thank you to the author for the ARC!! It was absolute delight to read!

Moss’d in Space by Rebecca Thorne
Moss’d in Space series #1. Cozy Science fiction adventure. LGBTQ+, slow-burn romance. Cliffhanger aka great hook at the very end.
Torian Razner will do anything to get her sister to a planet where she can breathe. She’s dying from the artificial recycled air. Finally, after 20 years of saving, she has enough to buy a ship. For that price, there isn’t a choice. The one and only ship available is an alien ship that was abandoned a hundred years ago and it’s covered in moss. It’s only as she’s aboard that she finds out that Moss is sentient and has abandonment issues. It doesn’t matter. She sets off to find a place her sister can live. A wormhole, an engine failure, a reroute and a ship graveyard are just the start of finding their new home.
🎧 I listened to an audiobook version narrated by Dylan Reilly Fitzpatrick and Natalie Naudus, the latter having over 400 audiobooks and both having done sci-fi and Romantasy books. The story is told in alternating POV chapters and each creates the two main voices in distinct voices or accents for the other. The voices are male and female so switches are easy to hear. More, Dylan is more computer and artificial mechanical voice though Moss is sentient. Natalie’s voice variances in conversations are amazing and I had to listen closely to determine if it was just person or more. Very impressive.
I will definitely watch for the next story. Especially if these two narrators are again onboard.
Loved Moss, and the banter. Plus Auto Nav!
Amusing, captivating and a great adventure.

This was delightful but also a lot more emotional than I had expected. The characters were great and their dynamics were incredible. It was a lot of fun to accompany Torian and Moss on their travels but also I bawled my eyes out at one point. Also love me some disaster lesbians in space. The narration is also fantastic and both narrators do an amazing job of bringing the characters to life. Definitely my favourite Rebecca Thorne book so far!

I really liked the beginning of this and I really enjoyed the writing. I would say the coziness of the first half of this book is similar to Becky Chambers' Wayfarer series, where the atmosphere is cozy but there are stakes and the characters find themselves in actual danger. Normally, that's the kind of cozy I prefer (I know there are some cozy fantasy enjoyers that would rather read something with no stakes at all), because otherwise I would be really bored. In this case, stuff was happening but I was still pretty bored and the plot just wasn't gripping me at all. I do really like the sentient moss character (called Moss!), who reminded me a lot of ART from the Murderbot Diaries albeit slightly snarkier. It was the best part of this book for me, but unfortunately I wasn't really interested in much else.

Moss’d in Space 🚀
By Rebecca Thorne
This was my first book by Rebecca Thorne, and now I need to read the rest of her work!
This fun cozy scifi about an abandoned moss covered ship was a fun read! Rebecca Thorne’s writing was perfect at capturing a light hearted atmosphere while still making you feel some tension from what our character is going through. The witty little banter between our two main characters was an aspect I really enjoyed!
The audiobook is so perfectly done, the dual narrators and their ability to give characters their own unique voices really brought this story to life! I will be seeking out more of their work for sure!
If you like cozy then this is a must for you!
What would you ask a plant if you could communicate with it? 🤔
Thank you Netgalley and Macmillan Audio for the ALC! 🙏🏼

I just wanted to say a quick thank you to the publisher for sending me an early copy of this book to review- all thoughts are honest and my own.
this book is what I would call the definition of cosy fantasy/sci-fi. we have diverse characters who would do anything for those they care about, travelling through rich space worlds and planets, exploring new and undiscovered elements of science and also stumbling upon to old items once forgotten. a range of personalities that shouldn’t work together but do, because they all in their own weird way gel together like they were always destined to be with one another.
I really enjoyed the found family elements of this. I enjoyed seeing a mix of species / elements grow and evolve to becoming the best versions of themself through friendships and care. I think having moss as a main character was a really fun and quirky way to help the story develop and it was an interesting choice to have the focal point of the story hinge from literally moss?? I think it was cringey and camp but in such a cute and fun way
I think my reason for this not getting four stars is I do think that the plot suffered in order for the characters to develop and grow close, which is fine because its a cosy sci-fi but it did leave me wanting more. I wanted to know more about the world, its history, the missing species and where they went, how humans ended up on these stations with different creatures and species. the world at times felt more like a back drop than an actual flushed outer world- it didnt ruin the story for me because like I said I love the characters, but it did leave me wanting more.

Moss’d in Space was a cozy, charming adventure with an original premise, but the execution left me with mixed feelings.
The sentient, snarky moss computer was a huge highlight for me and the banter between protagonist Torian and MOSS provided ongoing, excellent comic relief. Their dialogue kept me coming back to this book, and the found-family dynamic among the misfit crew was genuinely heartwarming.
However, the story frequently stalled. The pacing was incredibly slow, focusing heavily on slice-of-life spaceship maintenance rather than driving a cohesive story forward. Additionally, the highly anticipated sapphic romance was such a distant slow-burn that it felt like an afterthought.
I think in spite of these issues I personally had with the book, the writing was strong, and this may work for readers who enjoy very slow paced, cozy reads.
✦ 𝗔𝘂𝗱𝗶𝗼 𝗡𝗼𝘁𝗲𝘀 ✦
Natalie Naudus is one of my favorite narrators, and she once again brought her award winning talent to her performance of Torian’s perspective. I loved how she was able to capture Torian’s determination and grit through her tone. Dylan Reilly Fitzpatrick really leaned into the dramatics for MOSS’s lines and I loved how much sarcasm and snark he added to the character. Excellent comedic timing for both of these artists, and I highly recommend the audio if you’re interested in checking out this story!

Moss’d in Space is a sweet, cozy Sci-Fi story with several aspects I adored:
❤️ Sentient talking plant
❤️ Found Family
❤️ Cozy vibes
❤️ Funny banter
❤️ Zany side characters
Unfortunately, the story felt surface level. Most side characters were not fully present until at least the 60% mark in the story. Many obvious questions were not asked during the story. For example, why couldn’t Moss help fix one of the many existing human space station air systems? The situations lacked depth and complexity. Several injustices and issues were mentioned, but none were helped or solved, just stated and moved on from.
Thank you to Macmillan Audio for the gifted ALC of this book to read and review.
Torian, the FMC, is accepting, kind, understanding, and selfless. In my opinion, she is overshadowed by the true MC of the book: Moss! Moss is the sentient life support system on Torian’s new ship. They have abandonment issues and immediately identify Torian as its best friend. Moss is funny, snarky, nosy, and often struggles with forgiveness. I wanted more of the side characters in the story. I loved Dutch, Amelia, and Celise. Also, little Peet and Auto Nav!!!
The plot pacing was slow, with some plot points being a bit redundant and predictable. The author’s writing was smooth and entertaining. This is my first book by Rebecca Thorne.
This book lightly touches on weighty topics such as surveillance by computers, fully computer-controlled vehicles (in this case a spaceship), and the value of AI vs a book.
The world building is detailed in some parts yet basic in others. There is very little information on the smuggling companies or any political entities (human or otherwise). We learn very little about Dutch and his people and history. I am hoping more will be revealed in the next book, since this book ended in a cliffhanger.
The book narration was well done. Both narrators brought the story to life with their great character voices. I highly recommend the audio!!
This book does not contain spice or steam.
Overall, this was a sweet story with a hopeful message but lacked depth.

I am fairly certain that the bookseller of the local independent bookstore thinks I am insane. Why, you may ask? Well when she attempted to talk to me about the plot of Moss'd in space, I had to admit I didnt actually know anything about it, I just trusted the author would write something i liked so I preordered it.
But to my credit - I was completly right. I very much enjoyed Moss'd in space. This is a cozy style scifi novel about a woman's dedication for her sister and a sentient moss's desire for companionship. It's a story of a found family, who are also starting to learn that perhaps the world isn't as fair as it should be.
I love found family. It is one of my favorite tropes. I like the way that connections are built and relationships are developed. Thia story has very natural growth between the characters, and I really enjoyed seeing it.
I liked that there is romance in this book, but it is very slow burn. It is just kind of a background thread of this story, and there is going to be a lot of time to explore it in further books!
I highly recommend!

This was such a fun adventure!!
If you enjoyed the relationship between Grace and Rocky in Project Hail Mary, I’m sure you’ll find the bond between a sentient moss computer system and its pilot best friend equally compelling!
I really enjoyed this read! Thorne has a talent for crafting heartfelt characters, and her writing style is engaging. I appreciated Moss's character development throughout the story, and I found Torian's relationship with her sister to be compelling, even in its complexities. I personally loved the asthma representation with her sister as someone who is currently battling the asthma attacks that comes with spring/summer pollen.
This was an enjoyable and lighthearted (yet still emotional) book that kept me engaged.
Thank you Pan Macmillan | Tor for the digital arc.

Cozy sci-fi with heart and a grumpy twist. Torian Razner finally buys a long-abandoned alien starship to escape her dying colony, only to discover the moss coating the ship is actually Moss, a snarky, lonely organic computer with serious abandonment issues. What follows is a warm, funny adventure about unlikely partnership, healing old wounds, and building found family in deep space. Light on dense science but rich in charm, the story is perfect for readers who like character-driven sci-fi with humor, heart, and a cranky plant.

Thank you Macmillan Audio for the gifted copy.
This was such a cute, low-stakes romp through space with sentient moss, and honestly, that's enough to catch my attention. The pacing was a little slow at times, but overall I still found it to be a really enjoyable story.
The found family vibes were definitely the highlight for me, especially with the excellent sisterly relationship woven throughout the story. While it didn't quite give me the cozy feeling I was expecting, it also wasn't a high-octane sci-fi adventure. Instead, it felt like the kind of book that encourages you to slow down, enjoy the journey, and spend time with the characters.
🎧 Natalie Naudus and Dylan Reilly Fitzpatrick both did a wonderful job with the narration. They really brought the story to life, and they're both narrators I always enjoy listening to.

3.5 ⭐️
Thank you so much to the Macmillan Early Listeners Program for this ALC!
Moss’d in Space is a story that is a little bit outside of my personal comfort zone when it comes to stories. Torian is looking for a space ship, there are like space gangs, there’s talking moss, lots of stuff is going on. Overall, it all comes together for a very cozy sci-fi that worked well for someone just dipping their toes into this genre.
I love moss (as a plant). I’m also a huge fan of Moss, the character. Moss gives a similar vibe to Rocky in Project Hail Mary, which is delightful. Moss is sarcastic and funny, while also feeling and sharing deep emotions. I really appreciated it as a character and it was fun to get to see the world from its perspective.
Torian is a very dedicated and loyal character. Her entire purpose is to save those around her. Whether that be her sister or her “not romantic partner,” Torian will do what’s best for them. In a broader sense, she is also very self-sacrificing for the good of all humanity (and all alien life forms). She is such a selfless character to read and she is someone that wants to do good. It is easy to root for her.
There were parts of this book that took twists and turns that I was not anticipating. As someone new to sci-fi, it was at times hard to follow these parts, especially in an audio format. Despite some of my initial confusion, these twists kept me engaged to see how the story would turn out.
The multiple narrators for this book did a really great job. The different voices for different characters helped me to determine what was going on and it felt like listening to a movie at times. Highly recommend the audio, especially because I don’t think I would’ve had the correct pronunciations for most places.
Overall, I’d recommend this to anyone wanting a cozy, sci-fi story.

4.5 stars!! I really enjoyed this books!! I am loving the cozy books that are taking over and this one is no different.
Moss'd in Space is the first in a cozy sci fi duology about a girl who wants to save her sister who is dying on her home planet from breathing the recycled air. She buys a starship that happens to be "alien" covered in Moss that is actually a sentient super computer.
The two go on a journey to rhymarra, the only terraformed human planet in hopes they will be able to find refuge there for her sister!
I loved the plot. I thought it was unique and interesting with just enough tension to keep myself engaged through a cozy novel.
I absolutely LOVED Moss, the sentient moss super computer with abandonment issues. The character growth of Moss was so emotional and really well done.
The found family aspect of the book with all the side characters that they collected along the way was also amazing.
The only thing I didn't really love was the way Moss's chapters were broken down. I felt sometimes it pulled me out of the story and I wish they had just been placed in the story instead or something? For me it messed with the pacing at times. But I do understand that it was a choice and others will probably love it.
But overall I LOVED this book and can't wait for book two.

Book Riot’s Best Books of 2026 (So Far)
Cozy sci-fi + spaceship adventures + a sentient moss life support system with serious abandonment issues? Yes please! That would already be more than enough to win me over; but add in an overly optimistic heroine determined to save her sister's life, compelling sci-fi worldbuilding, and interesting alien species, plus a not-quite-unrequited romance, and you can see why I absolutely devoured this book. I guarantee you will too.

wdym it ends like that!! will absolutely be continuing this series. i'm normally not a sci-fi girly, but i'm SO glad i picked this up. i would die for Moss.
i listened to the audiobook and the narrators did a great job- Natalie Naudus is one of my favorites, conversational and able to differentiate between characters- and i loved Dylan Reilly Fitzpatrick as Moss!!
*i've seen a few reviews misgendering Dylan, I just want to point out they are nonbinary and their pronouns are they/them/theirs
Thanks to Macmillian Audio for this ALC!

I had no idea what I was getting into when I picked up this read. Sentient moss with abandonment issues? ARE YOU JOKING?? Moss just wanted a friend and someone to talk to? BRB I’m sobbing.
Moss’d in Space was hilariously punny and absolutely heartwarming. I loved how sassy Moss was and how it grew to befriend all the characters in unique ways. This little found family of lovable misfits was perfect for the story. I liked that it talked mad shit about the other plants and then began collecting friends intentionally and unintentionally. The little bits where Moss is trying to get to know people or learn new concepts was absolutely hilarious. I thoroughly enjoyed all of those micro moments that really brought the characters together. I’m kinda annoyed with the alien that created the Moss ship because what do you mean you just FORGOT where you left it for 100 years? I don’t blame Moss for holding a grudge because I’d feel abandoned too. Like you couldn’t have cared enough to take note? I’m not sure I personally ever forgave them but whatever!
While I know the point of the story was NOT about the romance, I’m a little disappointed that the MC’s romance didn’t play a bigger role. To me the romance kinda fell into a middle ground that I didn’t love: not a central part of the story yet not small enough to just be a detail about the characters past. It was a bit like being romantically edged the whole book.
I really enjoyed the cozy nature of the adventure that also had enough stakes to keep the plot moving forward at a decent pace. I definitely wish the stakes were a bit higher for my own personal taste, but i tend to feel that way about cozy stories in general. I am so curious to see what happens in future books in this universe (hello that ending can’t be it!)
I am an audiobook girlie through and through and I thought the Moss’d in Space audiobook was a lot of fun. The narrator’s voice for Moss especially was absolutely perfect and had me cackling multiple times. Truly the performance was truly top notch!

This is my favorite kind of reads: within the SFF genre, humor that adds some coziness, found family to hit you in the feels, lots of love but not too much romance, and still nailing some rather important themes.
Following Rebecca Thorne for a while now, I already knew she was a great person and writer, but I think that this book of hers is my favorite so far. The humor resonated with me perfectly, and as a biologist, I have enjoyed the variety of alien species and *the* sentient moss, and I'm always loving a story with a found family trope.
This story has a rich world and wide set of characters presented through a well-paced story that balances humor and emotion perfectly. It had a natural story flow with immersive dialogues that got you lost in the story. It features sisterly love, human-moss friendship, multi-alien-race found family, and just a speckle of romance, that's delightfully queer and sweet. Even though it was a minor part of the book, I loved the little jab at the privileges of getting academic education, as that's such important commentary.
I've read this as an immersion read with an ARC received from Pan Macmillan/Tor via NetGalley and a self-inquired audiobook copy, as I could not resist the narration of Natalie Naudus, who's one of my favorite narrators to date. For anyone who enjoys audiobooks, I definitely recommend this format for the best story experience.
I usually dislike when a book is marketed as a crossover between some other books or author styles, but it's true that this carried some of the Murderbot personality vibes, as well as some Becky Chambers coziness. If you go in expecting that, you won't be disappointed.
I just can't wait for the sequel to come out!

Review of advance copy received from NetGalley
Cute and cozy SciFi adventure featuring sentient moss and a solid plot around with a background of social injustice.
I liked the concept of the sentient alien moss that is the life support of a spaceship. I didn't entirely understand how it worked, but it was feasible enough given the alien aspects that I was happy to roll with it. I also really appreciated that Moss had its own voice and POV chapters, rather than it just being a companion side character.
The plot follows Torian, and engineer turned scrapper who is determined to bring her chronically ill sister to the only terraformed human-inhabited planet to save her life, no matter how few people believe in her being able to do so. But to get her from the station they live on to that planet, she needs a ship. And when the alien, moss-covered one is the only one she can afford, she never would have guessed what hides behind the green life support system.
There is a sapphic romantic subplot that is quite nice, a lot less dramatic than I thought given how antagonistic the two are towards each other at the start. I also really liked all the different aliens and futuristic tech.
The social justice subplot was rather small, so I think there is some untapped potential there for future books, though the epilogue already sets up a different plot for the next book.
I received an ARC and reviewed honestly and voluntarily.

Thanks to Bramble, Macmillan Audio, Rebecca Thorne (author), Edelweiss, and Libro.fm for the digital review copy and advance audiobook copy of Moss’d In Space (narrated by Dylan Reilly Fitzpatrick and Natalie Naudus). Their generosity did not influence my review.
There is a fairly new sub genre in the literary sci-fi world and a lot of people really love it. A “cozy sci-fi” book is one with a ragtag group of found family that usually includes a mix of humans, aliens, robots, and maybe even plants going around and having fun. They bicker like siblings but ultimately love each other dearly. You don’t really get much in the way of background for the characters, and that’s okay because the plot of the story is only important for building the relationships and group dynamic. Think Guardians of the Galaxy when they were between Thanos crises adventures.
Moss’d In Space begins with the human Torian purchasing an old, abandoned spaceship only to find that the moss growing inside is a snarky, sentient computer with abandonment issues. They, of course, learn about each other and become new best friends on their adventures that are not world-saving or galaxy-altering quests. Just normal life stuff, and that’s not to say that I didn’t get a lump in my throat from time to time because I certainly did. However, I did have some issues early on with the author writing as if the reader is unable to understand without saying something repeatedly. It was an irritating and obvious repetition of very basic things like names and occupations, but it improved as the story went on. 3.25 stars

I loved this book so much.
Cozy sci-fi is absolutely my jam, and this book reminded me why I can’t get enough of it. It has the perfect mix of humor, heart, adventure, and characters that feel impossible not to love.
The standout for me was Moss. Every time Moss appeared on the page I was completely invested. The audiobook made the character even better, and those chapters were easily some of my favorite parts of the entire story. I found myself laughing one moment and getting surprisingly emotional the next. Seriously go listen to this one the audiobook is fabulous I immersive read and what a fun experience!
The found family aspects were wonderful, and I loved watching this quirky group come together. The story has that cozy feel I love, but it never felt slow. There was always something happening, and I was completely immersed from beginning to end.
Rebecca Thorne has been an auto-buy author for me for a while now, and this book is exactly why. She consistently creates characters that feel unique, memorable, and full of personality. By the end, I wasn’t ready to leave this world or these characters behind.
This book left me happy, entertained, and immediately wanting the next installment. I honestly can’t say enough good things about it. If you love cozy sci-fi, found family, lovable oddballs, and stories with a lot of heart, I highly recommend picking this one up.
One of my favorite reads of the year, and I’m already impatiently waiting for more. Thanks to Tor publishing and Macmillan audio for the arc.

This book was pure fun.
I absolutely love Moss and especially Moss's view of humanity. Moss at times feels like a sentient AI, but made from moss, who can control the ship that Torian buys in a bid to get to a planet that may be able to help her sister. The snark from Moss combined with the found family that is built throughout the story and the fact that is cozy sci-fi, put this one straight into my favorites category for this year.
I've loved everything Rebecca Thorne has written but this one certainly felt extra special.
The audiobook narration team of Dylan Reilly Fitzpatrick and Natalie Naudus was perfect. I am always excited to listen when Natalie Naudus is a narrator and Dylan Reilly Fitzpatrick was excellent as well on this. I may need to add them to my auto-listen list.
Thank you Tor Books and Macmillan Audio for the eARC and ALC. All thoughts are my own.

Not sure how no one else has mentioned this in reviews so far. Maybe it’s my profession, but I was so bothered by mistakes in the first 13 pages that I could not read on. When a book is published by an imprint of Tor, I at least expect some copyediting.
For example: the first three entries chronologically follow each other yet their dates are 90111, 90011 and 90113. The middle date should be 90111. This wasn’t bad, because it’s a simple error and easily overlooked.
But…chapter 1, paragraph 3 is this mistake: “…on the long walk tottt the…” What even is that? Even basic spellcheck will highlight that.
I hate to DNF a book without giving it a couple chapters, but this is going to be an exception.

This was a highly anticipated release for me because I love Rebecca Thorne’s style, and it definitely lived up to the hype. Cozy sci-fi is a genre I for sure need more of, because cozy fantasy is so prevalent but this was exactly what I could’ve wanted. The characters were all fantastic, Moss especially and I totally get the Murderbot comparisons.
I also like how this set up so much for another entry while still feeling like the characters grew throughout the story. The universe Thorne created is so interesting and I’m glad we get to explore it more.

These types of books - cozy fantasy, like Legends & Lattes - just are *not* for me. I don't see the point of them. Yes there's danger, yes there's sometimes "violence" (guns that shoot jelly bullets) but it just feels so YA (or "New Adult," which to me just feels like YA ashamed to bear that label) for me to actually enjoy it. The writing is fine, it's just absolutely not what I enjoy.

This was so cute I can't beleaf it
