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!

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!

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.

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.

THANK YOU TO THE AUTHOR FOR THE ARC, I AM OVER THE MOON. THIS IS A 100% HONEST REVIEW.

I adored every inch of this masterpiece. I love Rebecca writing, I always will, and I just felt so warm and fuzzy while reading this cosy adventure and it gave me such a heart warming feeling and its everything I could have wanted in a cosy sci-fi book. I adore these characters, I adore the puns and the jokes and the setting and everything about this.

Rebecca is one of auto-buy authors, I find that she writes such lovely but complex and beautiful characters. They’re so weird but in a good way, they’re not afraid to be them and I find when I read her books I find a safe space to let myself be me. I will treasure these characters and hold them in my heart 🥰💖 Rebecca’s stories mean so much to be personally and I recommend everyone who loves cosy books to give this one a try.

This was such a cute and cozy read. I’m not always a big fan of cozy books but this book caught my eye. I am beyond thrilled to have been accepted to listen to this audiobook early. I loved this book. It was exactly what I needed. The characters are well-written. The plot of the story was interesting. The star of the book has to be Moss the sentient moss. It is hilarious. But what made me like Moss was that the cast of characters was also great. I’m excited to see where Book 2 is going to go.

The audiobook was excellent. Natalie Naudus and Dylan Reilly Fitzpatrick did a great job with the audiobook. The cast of characters all felt distinct and overall made it an enjoyable listen. I would highly recommend the audiobook! It’s perfect to put on while doing chores or a hobby.

Thank you to NetGalley, Rebecca Thorne, and Macmillan Audio for the ALC in exchange for an honest review.

This was so cute, such an enjoyable cozy sci-fi read! As a huge Wall-e fan, I got a lot of those similar vibes mixed in with, of course, everything we love about the Times & Tea series.

I loved the sense of humor in this that had me chuckling multiple times, and the adventure was a great time. It was well-paced without feeling like we were “stuck” in any one spot for too long.

If anything, I wish the romance was just slightly *more,* but I’m excited to see how it develops in the next book!

Thank you Bramble for sending an ARC to Hearthside Books. I am so ridiculously excited to read this right now.

As always, Rebecca Thorne writes something and I will read it. I still need to catch up on This Gilded Abyss and that'll be my next read when I finish my LOTR read with my friend from work.

Since this isn't out until July, my short & sweet review is this: This book is the start of a new Cozy Science Fiction series. I thought the characters were adorable and Moss is a great POV. This is a soft read with a lovely found family vibe with the new characters we meet along the way. I can't wait to see how things play out next!

*Thank you to Net Galley for this ARC*

I absolutely adore Rebecca Thorne's writing, every single book I've read (literally ALL of them) draws me in instantly and Moss'd in Space is no different. I love the main character, Torian- she is just a lost lady looking for anyway possible to save her sister. She's so relatable and I loved her journey of self-discovery. I'm so excited to see what's going to happen with Torian and Amelia's relationship in the second one.

Now for my favorite character, MOSS- this is a moss with an intelligence system and it's funny. The talk of sass and sarcasm is my absolute favorite. I am digging how lots of fantasy worlds are queer-normative, Moss's in Space is another one to add to that list. It's always refreshing to see when not every book with queer characters has to explain itself. Also, loved the autism representation with Lyric and they're relationship with MOSS.

Rebecca writes and fantastic story and I will forever read anything she writes, please write all the lesbian fantasy books you can, they give me life!!

Thank you to the author and NetGalley for giving me an ARC.

Although I wasn't sure about this book in the first few chapters, it absolutely won its way into being a 5 star book for me by the end. I absolutely loved all of the characters, especially Torian and Moss. The dynamics between all of the characters were so well done and I found myself having so much fun reading this. The dialogue his hilarious at times and heart-wrenching at others and I loved all of it.

Torian and Amelia had a complicated relationship; they clearly love each other but Amelia has a lot of past trauma to work through, and Torian recognises that she hardly knows Amelia as a person at all. I really liked that once they met up again they didn't immediately get back together. Both of their characters need time to work through their own stuff and to get to know each other as friends first. Dutch and Zen's relationship was such a delight. I'm a sucker for an interspecies relationship and they were so fun together. I really liked how they worked together and saw each other as equals despite coming from vastly different cultures. Their dynamic was so sweet and silly at times and I loved them.

Torian is an instantly likeable character. She is stubborn and dedicated and will look out for her friends at the cost of her own self-preservation. Her optimism and steadfastness about finding better living conditions for her sister was so admirable, and I love that she never gave up despite facing set-backs. Dutch was a really interesting character. At first, I disliked him because he left Moss behind and Moss was undersatandably deeply angry and hurt about it. But Dutch was truly remorseful about leaving Moss behind and an incredibly complex character. And finding out that he also knows what it feels like to be left behind demonstrates that he wasn't being malicious. Nastra was great, I loved the detail of her always being in a hive mind with others of her species, and the sheer curiousity and love for learning that she has.

I didn't realise that this was the first book of a series when I applied for an ARC but I'm so grateful that it is! I felt there were a few questions left unanswered, especially around Dutch and where his people went, and I also just love the characters and I'm incredibly excited for them to return in the next book.

This is definitely one of Rebecca Thorne's strongest books.

The queernormative world and diversity was so lovely to read. It felt so effortless and was seemlessly woven into the narrative, but it meant a lot.

This wants to be The Long Way to a Small, Angry Planet, but to me it really fell short. With TLWtaSAP, Becky Chambers built a world where there's no real villains and the science part of the sci-fi might as well be magic for all that it doesn't try to offer explanations, and Thorne is doing the same here. But while I didn't mind Chambers's handwaving away algae propelling a starship, I seem to have less patience for Thorne talking about a nebula that is within a solar system rather than being thousands of times larger than one. Partly this is because Chambers is much better at the actual handwaving: she gives a minimum of detail, so I'm not caught out by things that are obviously incongruous to me, and can instead vaguely fill in the blanks or just ignore it; Thorne makes the mistake of trying to provide explanations that don't make sense.

Mostly, however, this book fails to be TLWtaSAP because the characters fail to feel like proper adults. Instead, they all just read as quirky Tumblr creations, full of impulse and bravado and anxiety and not in fact much sense. I can tolerate that for a young, twenty-something main character, but I can't really tolerate it for an almost thousand year old alien plant intelligence or their alien creator. Ashby and Sissix and Doctor Chef and the rest from TLWtaSAP read as adults to me; they're quirky and fun, but react to blockers and inconveniences in a way that suggests that they have a wealth of experience behind them and have a life story that is more than just a few tropes thrown at the wall.

I love cozy fiction, but there's a real sweet spot that needs to be hit to make the mood sit right without being saccharine. This doesn't hit it for me.

More reviews (and no fluff) on the blog http://surrealtalvi.wordpress.com/

This is a cozy type of book that wears its heart on its sleave and is sweet enough to induce cavities. And yet, somehow it felt rather aimless and flat: a non-threatening female lead who is dumb as a doorknob but blessed by the universe, a bunch of side characters that should be quirky but instead can be annoying and oddly over-the-top, and a plot that goes no where fast. Of note, I listened to the audio narration and while the female narrator was fine, I found the male narrator to be annoying and distracting.

Story: Torian's sister is dying on the backwater colony they are stranded on. Without fresh air, her sister will cough herself to death. Torian works security on a fleet ship until she gets enough to buy her own little vehicle, one she will use to fly to a planet in which she hopes to get citizenship and bring her sister to clean air. Unfortunately for her, the ship she buys is inhabited by an alien moss organism with abandonment issues. Can she get the moss to help her save her sister?

So no, I'm not a fan of bumbling nitwits who are improbably blessed by the universe. Fans of Apprentice to the Villain, A Long Way To A Small Angry Planet, etc. will likely enjoy this harmless little fluff of a book. For me, I kept wishing the intelligent moss was more of a sarcastic Murderbot rather than a bland and endlessly monologuing sad sack. All the characters overidealized and as unrealistic as you can get. Everything works out perfectly in the end and you just ignore how improbable and illogical this story was in favor of the niceness.

So yes, it was a bit too simple and one-dimensional for me. Definitely not my cup of tea. Reviewed from an advance reader copy provided by the publisher.

If you love the relationship between an FMC and her sentient plant in Sarah Beth Durst's The Spellshop series, but fancy a sci-fi setting rather than fantasy, Moss'd In Space is definitely worth picking up!

It's the first book in a new cozy sci-fi adventure trilogy with a very slow burn sapphic romance subplot, but so far the greatest relationship in book 1 is between our FMC Torian and the sentient Moss that now controls Torian's recently-acquired spaceship. Torian is a very self-sacrificing and loyal person, so she's well matched with Moss, who has abandonment issues and snark for days. The banter between Torian and Moss is fun, particularly when Moss starts to gang up on Torian with a variety of other characters about her lack of self-preservation.

This first book does a really good job of setting up the next two books in the series for success. It doesn't try to accelerate through the plot or relationships, and instead takes it nice and slow, which works great for a cozy sci-fi series. The romantic relationship between Torian and smuggler Amelia is only in its very early stages here in book 1, which shows great promise for a gradual progression in their relationship. When a relationship goes from 0 to 100 in book 1, I often find that book 2 doesn't leave much space for the relationship to develop further. That's not the case here. Moss'd In Space shows the chemistry between Torian and Amelia but doesn't push them together too quickly. Book 1 also does a good job of establishing a heartwarming found family that will continue to develop in the next two books.

Overall, Moss'd in Space is a great start to this cozy sci-fi trilogy, and with the world and characters established now, I'm really hopeful that the next books will have even more of an emotional impact and dive deeper into some of the relationships.

“I have heard good things about ‘dreams’, although it is strange you hallucinate vividly each night and claim it is healthy.”


Moss’d in Space is a wonderful cozy SciFi story that includes some of my favorite things: space travel, great humour and - best of all - a lovable, snarky and hilarious sentient plant named Moss (and a FMC that is equally quick-witted!).

The author stated that she was inspired by Murderbot, which I can totally see but I love the direction she took Moss from there! I do see some of Murderbot’s characteristics in Moss but also, it feels a bit like a mix of a golden retriever and a cat - it is ready and waiting for praise, loves you, but judges you nonetheless. :D

The book focuses on Torian Razner, our FMC, who has just bought her very first starship. What she didn’t expect when buying said starship in order to leave the space station was acquiring a sentient life support system that has abandonment issues along with it. Now she’s traveling through space with a new buddy and even though all’s not well, at least she’s not alone in her quest.

Overall I found all of the characters to be very likeable, the story had a very nice flow and I nearly read it in one sitting because I didn’t want to put it down. The humour was very well done, the story cozy but included several emotional or tense sections as well. I already can’t wait to reunite with these characters in the sequel and I’m so happy that R. Thorne decided to write a cozy story in space!


Thank you Netgalley and Pan MacMillan/TOR for providing me with this advanced readers copy!

Moss’d in Space by Rebecca Thorne
Torian Razner has saved enough to buy a starship. Unfortunately, she can only afford the cheapest one available, an alien craft which has been sitting abandoned for well over a century. And whose interior is covered in moss. But Torian is desperate to save the life of her sister who needs to move to a planet with better air than is found on their space station.
Then she discovers that the moss is Moss, ‘the only organic computer in existence’, and it controls the life-support system. And much else besides. She is in for a steep learning curve.
Torian’s skillsets are ‘suboptimal’ in Moss’s opinion, but she is open-minded, has a good heart, and is passionately loyal to close friends. Which turn out to be the right qualities for making friends with aliens as well as organic computers with abandonment issues. As one character observes, ‘You haven’t let the world change you. You’re still hopeful and determined and you see the best in everyone.’
Will these prove enough to save the life of a sister who as a devoted medical doctor is reluctant to leave her patients, however?
This is entertaining science fiction, marked by a lively pace, an amusing interplay between interesting characters (including the AI enhanced computer systems that run the starship), and a refreshingly balanced view of aliens that recalls the novels of Gordon Dickson.
Strongly recommended.

3.75 rounded up

The premise of this book is the perfect setting for a cozy sci fi; sentient space ship, family in need, putting aside difference for said family. It has all the ingredients it just needed a little pizazz.

As most cozy stories are, this was a little more character forward than plot forward which is generally ok but I felt like I needed another character; like someone was missing? The central plot is solved pretty quickly in the second half the of the book, but the first half seemed to be Torian and Moss conversing a lot and not a lot of plot advancement. I thought the romance was really well done and not at all the focus of the book (in a good way). I only read one other of Thorne’s books and the style was pretty similar so if you like the Tomes and Tea series you’ll almost definitely like this.

The audiobook is dual style and I really liked the female narrator. However the male narrator decided to only use male voices for all the characters and it made it more difficult to tell who was speaking sometimes. Great job with the moss voice but it sounded almost the same as the FMC.

The story ends and then a new scene ends on a “cliffhanger” to try and soft launch this as a series. This can be read as a contained story and I don’t think I’m attached enough to these characters to read another book about them.

Thank you to Netgalley and MacMillian Audio for an early copy of this audiobook in exchange for an honest review.

A sentient moss with abandonment issues has no business being this charming, and yet here we are. Moss’d in Space is cozy, cute, and packed with just enough chaos to keep this bizarre, overgrown spaceship feeling unpredictable. The stakes are real, but they never crush the tone. Rebecca Thorne keeps the story grounded in the characters, their relationships, and a few carefully chosen locations instead of trying to tour every corner of the galaxy.

That choice works beautifully for a standalone sci-fi. The world feels full without being overstuffed, and the heart of the story stays exactly where it should: friendship. Old friendships, new friendships, fractured friendships, the terrifying vulnerability of wanting to be chosen, and the very relatable urge of a lonely sentience to acquire a new best friend. Moss has wit, attitude, and enough charm that I finished the book fully prepared to adopt emotionally needy vegetation.

🎧 The audiobook is excellent. The narrators absolutely nail the personalities, especially the contrast between the flora and fauna energy. It would have been ridiculous fun as a duet, but even as-is, the performances make the humor and emotional beats land beautifully. Honestly, this book feels like getting emotionally manipulated by a houseplant, and I mean that as the highest compliment possible.

Thank you to NetGalley for the advanced copy

Torian Razner is looking to escape her troubled colony and her ex with her sister. After spending all her funds purchasing an old starship, she is surprised to learn it also comes with a new friend.

I really LOVED Moss, my favourite character in the book for obvious reasons. I mean, it's a plant with abandonment issues! I really like the arc with Moss' old captain. It was funny and heartfelt; all the Moss backstory worked for me. I honestly would have enjoyed an entire Torian and Moss hangout in space book. I loved Moss making more connections with people/ship programs through the book, realising that it won't be left alone again. Loved all that. There are quite a few secondary characters I also really enjoyed; there's a lot of potential there with future books.

I will say I wasn't that invested in Torian's romantic subplot; perhaps Amelia will get more fleshed out in future books. I actually didn't really "get" her character until the last chapter or so. Given that she was her boss and she demoted Torian, I was kind of mad at her for a lot of the book!

This is a super cosy, funny, heartfelt book. I do recommend it, and I hope future instalments build out the other characters introduced :)

Thank you to Macmillan and Netgalley for generously providing me with an ALC of this book. All opinions are my own.

If you are familiar with Rebecca Thorne’s work (Can’t Spell Treason Without Tea, This Gilded Abyss, etc), you can expect the usual found family and cozy-adjacent vibes while raising the bar overall in what I believe to be her best work yet.

Delving into the scifi and humor space in books, the atmosphere, pacing and writing here is perfect for fans of The Jinn-Bot of Shantiport, Muderbot, and Redshirts. Are you an old-school fan of Farscape? Friend, have I got the book for you. A diverse cast of humans, aliens, and machine and plant intelligences will simultaneously grab you by the heart strings and the funny bone and not let go. I had a marvelous time from start to finish.

In particular, the narrators for the audiobook were perfectly chosen. Natalie Naudus is always an exceptional narrator and performer, and perfectly captures the sarcastic, irreverent and warm nature of the protagonist, Torian. Likewise, Dylan Reilly Fitzpatrick as the voice of the ship had me absolutely rolling on multiple occasions as the deadpan, yet fussy and dramatic Moss. I highly recommend experiencing this as an audiobook or as an immersive read if you are able.

Moss is the heart of this book. Yes, THAT moss - the stemless, rootless plant that reproduces via spores. Moss is also a sentient main character of this book, having integrated with the AI powering an alien spaceship's life support technology.

Moss' voice is dry, precise, and helpful in the most utterly irreverent way possible. Think Data from Star Trek: earnest, literal, and way funnier for it. The author said in the acknowledgments that Moss came to life in her brain after reading Murderbot, and it shows. Fans of Murderbot will feel right at home. At one point, Moss describes a new acquaintance as having, "like other humans", "a bipedal shape, a number of limbs, and features". Ha!

The author also said this was the book she was "dying to read: something cozy, comforting, fun, and humorous". She delivered it here with a fresh sci-fi flourish. Spaceships, botany, romance, aliens - this book has it all, set in a world so immersive and filled with characters so lovable that finishing this was bittersweet. Fortunately, a sequel is on the way, and if this book is any indication, the best may be yet to come.

Thanks so much to the publisher for my early copy.

I would love to express my gratitude to the publisher and the author for providing me with an e-arc copy of this amazing book.

This book follows a group of people, both flora and fauna, and even artificial, as they make their way through the galaxy in search of a place to survive and thrive. I think what makes this book stand out is the character Moss, a sentient moss colony connected to a biological computer through which it can communicate verbally with its friends. I loved Moss SOOOOO MUCH and want more of it!

The story is about relationships. The relationship between two sisters, two not-quite-ex-lovers, two former friends, and between the human species and some non-human alien species. There is commentary about love and hatred, forgiveness and memory, and class and privilege. It has moments of hilarity and emotion, and I loved it soooo much! I look forward to the second book whenever it comes out (I’m thrilled that there will be a sequel!). This is my first Rebecca Thorne book, and I look forward to dig into her other books as well!

Considering I DNFed the Treason series less than 6 chapters in, I was pessimistic about this, but Moss’d In Space kept me interested the whole way through, even when some of the pet peeves would have had me putting a different series down (looking at you, cutesy ‘implied cursing/using child-friendly versions of curse words but won’t use the real word’ in a novel for adults – it’s not cute, it’s annoying – especially when the characters in this book are supposed to have a “hardened” past as a smuggler/bodyguard. Like, I get this is a cozy novel, but the characters are still adults. Come on.)

I digress – I still enjoyed the rest of the book. Moss was a fun variant on your traditional sentient AI, being botany-themed. I prefer a developing relationship to a 2nd change/established (which this author seems to prefer based on previous series), but it wasn’t a deal breaker for me, even if I did spend most of the book hoping Torian would have a meet cute with someone else. It was a fun read, and I will read the sequel once it’s out.

⭐ 4.5/5 ⭐

Copy provided by the author and netgalley in exchange for a fair review.

Torian buys a ship with hopes of traversing space to find a cure for her sister's lung condition. She gets much more than she bargained for when the ship she buys is controlled by sentient moss.

- I adore cosy scifi, especially alien or space based, and this hit the spot. Whilst there were trials to overcome, the whole book was pretty chilled. I loved the different alien races Thorne has created and how they described this world. Although not as detailed, it reminded me a lot of The Wayfarers series by Becky Chambers.

- The characters were pretty cool though sometimes the humans felt a little flat. I loved Moss though and its quirky and prickly nature. 

- Like all of Thorne's other books, this one also centres queer relationships and identities. I do enjoy worlds where being queer is normal and people just exist in their lives without debate.

If you like cosy and queer sci-fi with fun non-human characters then I highly recommend Moss'd in Space.

⭐️⭐️⭐️⭐️.75/5

Moss’d in Space is a quirky, vibrant, and cozy sci-fi novel.

I had a blast with this one. The rich world-building—immersive, creative, and mossy—swept me away. I especially loved the descriptions of Torian’s starship and the different locations she, Moss, and her friends traveled to. I also adored the exploration of technology and space. The cast was hilarious, vivid, and well-developed, and I especially enjoyed Torian’s heartwarming relationship with Moss, her addictive romance with Amelia, and her beautiful, complicated relationship with her sister. The plot was engaging and twisty, and the pacing fit the story nicely. Rebecca Thorne’s prose was sweeping, welcoming, and witty, presenting a simultaneously exhilarating and cozy sci-fi adventure. I highly recommend this spectacular read!

Dylan Reilly Fitzpatrick and Natalie Naudus were excellent narrators. Their voices captured the characters brilliantly, presenting an even more atmospheric and heartwarming read. I highly recommend the audiobook!

Thank you to the publisher for the free ALC and ARC!

Moss'd in Space is exactly what it says on the tin - very cozy and cute, and a bit gay. Moss (the moss!) was far and away the highlight for me, though the auto-nav and engine are adorable bit players. It's definitely on the cozier side of cozy sci-fi, though there's enough talk of spaceships and terraforming that the setting doesn't feel unimportant or interchangeable. I found FMC Torian and her love interest Amelia a bit underwhelming - that's possibly because their relationship predates the start of the book, though it's not fully established like in Tomes & Tea - and there's a fair bit of time spent on character development. Still, Moss'd in Space is sweet and plenty of fun, especially if you're a fan of talking plants in your SFF. (The Spellshop fans - run, don't walk!)

Lovely narration by both Natalie Naudus and Dylan Reilly Fitzpatrick, who does an especially great job with unique voices for Moss and the many other characters. Thanks to NetGalley and the publisher for the audio ARC!

What a treat! A sentient plant-tech hybrid with a snarky voice delivers deadpans-- fans of All Systems Red will want to preorder this now (or place those library holds post-haste)!

This is cozy and managed to not be as silly as Can't Spell Treason Without Tea(/series). The space setting is general-- readers don't need to have a strong sci-fi background, anyone who has seen a few sci-fi movies will muddle along just fine. I didn't love that it ends on a literal cliff-hanger: be advised, if this would annoy you, to perhaps wait until the series is complete.

I had such high hopes for this after the tomes & tea series and let me tell you, it DID NOT DISAPPOINT 🙌🏼

I loved the whole cast of characters in this, but we follow our main characters, Torian (hard working and brave but with total imposter syndrome and a sister with a life threatening illness that she is determined to fix) and Moss (a sassy, sentient organic computer system that lives within Torian’s newly purchased spaceship and has serious abandonment issues) as they head out on an adventure that takes them across the solar system. Along the way, they help each other to tackle various challenges and develop an absolutely delightful friendship.

This had all the cosy sci-fi feels but with enough stakes and purpose to the story that it kept the plot moving. I think this is my perfect book right now. ***sighs in contentment***

Thank you to NetGalley and the publisher for this ARC in exchange for my honest review.

This is cozy sci-fi in the style of Becky Chambers. And I loved it. I was hesitant to even read it, after bouncing off the author's previous series, but this one hit where that one missed for me.

I love Moss. It's definitely the best character with personality for miles. All of the other characters are really good too, especially all of the aliens. And Autonav was delightful, as was Moss's alien creator and former owner.

The narrators did a fabulous job bringing the characters to life. Natalie Naudus is always excellent, but Dylan Reilly Fitzpatrick was outstanding as Moss, Autonav, and Engine.

The plot relies strongly on vibes but it works better here than in the author's previous books. There are less obvious plot holes and things that don't make sense.

I had the best time listening to this audiobook and I highly recommend it.

i just finished the tomes and teas series and was so sad to leave the world and characters behind. then the universe decided to bless me and i was chosen to get the readers arc for moss’d in space for rebecca thornes campaign!! this book has just as lovable characters with the same humor and wit that i loved so much through t&t!! moss was amazing, and i can’t believe i can say auto navigation is such a great character addition😂 also the way she is able to involve real life problems into a whimsy happy ending world just creates the perfect escape and makes me so happy and giddy to read!! im so happy i got the chance to read this early but i am so sad i have to wait SO LONG until the next installment of the series!! all in all amazing book, read it when it comes out, and add rebecca thorne to your list of favorites!! (this is my 100% honest review and is based on my opinions reading!!)
