The chance to be the first people to travel space and discover alien worlds could be the opportunity of a lifetime--or the end of one. Cargo Hold 4 is a gripping, suspense-filled science fiction horror, where nothing is as it seems and even your closest friends might not be who you think. An alien presence trapped in the cargo hold on an isolated space ship pushes a close-knit crew to the edge of madness, past the boundaries of mortality they believed in on Earth. By the end, the horrors within the ship compete with the horrors they brought from their own psyches. If you like your science fiction action packed and thrilling, this is the book for you.

Cargo Hold 4 has a well written storyline which takes place in outer space on a ship referred to as Gretel. This book was like watching a movie although I was reading. It’s gripping and pulled me all the way in. There aren’t any boring chapters which lead up to the next occurrence that unleashed the suspense. Every time I put the book down, I still had scenes going through my mind… just waiting for a free moment to pick it back up to see what happens next.

The main attraction is the writing style and how the characters interact with each other. Which brings the story to life and realty. Although there’s some bizarre things going on in Cargo Hold 4 of the ship that was surely out of this world. The crew of Gretel are thrown into fear and survival mode while working together to complete their mission. My favorite character is Hurd, as he isn’t quite the all around every day human.

Lonnie Busch has impressively taken his readers on an action packed ride into the depths of outer space. Where life meets new life. A must read for those who like space mysteries with a great plot! If you’re a fan of Sci-fi fiction and extraterrestrial entities then I definitely recommend reading this book.

It was very much a diabolos ex machina ending for this one. The creature just kept pulling new abilities out of nowhere throughout the story, seemingly as specific counters to whatever they tried. First it was seemingly incoporial and didn't show up on camera, until it did, then for some reason it could be heard by people who'd seen it but nobody else, then it was a giant slime creature etc.

There's a term I heard called "Monster's Perogative" which is essentially that a monster can do anything it hasn't been explicity established as being unable to do. It's mostly used in tabletop games as a way to keep tension when players are being overly clever by creating a way for the monster to still be a threat. It works in that context because creating a challenge for players is the point and it stoping actual thinking people, who are capable of unpredictable behaviours, from exploiting knowledge they have from outside of the game world to win too easily and making things boring. In a story where the writer controls both the monster and the hero, it's just lazy and undercuts the narrative of the characters trying anything because even if the author creates a situation where it seems like the heroes should survive/win/whatever, the monster can just manefest a new way to win that isn't possible to predict by either the characters or the reader.

Plus the mission is clearly being run, and crewed, by idiots. The ending is partially brought about by ostensibly highly intelligent people making some of the dumbest possible choices under the circumstances, completely unprompted.

Perfect for Sci Fi fans, Cargo Hold 4 delivers full doses of action, intrigue and all the necessary interplanetary weirdness we expect from a novel set on a spacecraft worlds away from Earth. Let’s not stop there however, as this tale has enough mystery, relationship drama and suspense to appeal to fans of other genres.

Lonnie Busch is a master of weaving an entertaining read that you can’t put down. As with his other books, I found this one screaming out to be adapted to the screen. It was so easy to visualise the events and empathise with the characters.

I received this arc from the author in exchange for my honest review.

Cargo Hold 4 is a Science Fiction/Horror novel by Lonnie Busch that takes the old trope of a stowaway aboard your spaceship to a different level. Perhaps the most famous example of having a stowaway aboard one’s spaceship in a Science Fiction movie is Alien. In literature and in movies, the trope of having a stowaway aboard a ship or even a train is a time-honored one. As with using any trope, it’s what an author does within the framework of one that attracts and holds the attention of the reader or fails to so. If you are a fan of the Science Fiction genre, I’d highly recommend that you check out Cargo Hold 4, a book that plays within the framework and also one that held my attention from the very beginning to the end.


I don’t want to mention many spoilers, but it’s not a very big one to say that there’s a stowaway aboard the Gretel, the spaceship of interest in Cargo Hold 4. The woman commanding the Gretel is Captain Desna and Berlin is the spaceship’s First Mate. One twist here is that the rather noisy and troublesome stowaway is somehow not an organic being. According to the book’s very first paragraph:

“Everything they’d discovered on Planet J–S was stored in Cargo Hold 4, but none of it was organic, according to their scanners.”

I won’t give away how Busch deals with this issue. My desire to read how this could happen was one of the things that made me want to keep on reading, so I don’t want to ruin anybody else’s pleasure. Suffice it to say that Busch’s solution to this apparent problem of a nonorganic stowaway aboard the Gretel was a pretty cool one.

One of the other problems Captain Desna and her crew is confronted with is the ethical one of deciding exactly what should be done about the irksome stowaway. Two of the other things making life difficult for Desna, Berlin, and everyone else aboard the Gretel include the necessity of their handling an unplanned spacewalk and also how they should attempt to dislodge the unwelcome alien that had stowed away in Cargo Hold 4.

I asked myself as I read Cargo Hold 4 questions like: “Is the book’s plot fast-paced?” “Are the complications that Captain Desna and her crew have to deal with dealt with in a realistic way?” and “Does Cargo Hold 4 have a plot that holds my interest and keeps me want to keep on reading it?”

I’m glad I read Cargo Hold 4. Besides being a captivating, page-turning Sci-Fi/Horror thriller, I liked reading the book for the added reason of discovering how the book’s author, Lonnie Busch, came up with inventive ways to play within the confines of the stowaway trope. I highly recommend Cargo Hold 4 for anyone who enjoys reading intelligent, fast-paced examples of the Sci-Fi/ Horror genre. Check it out today!

Cargo Hold 4, by Lonnie Busch, is an engaging piece of science fiction that plunges readers into a suspenseful and eerie journey through space. The story follows the crew of the spaceship Gretel, tasked with collecting samples from distant planets for research. However, their mission takes a terrifying turn when strange, roaring noises aboard the ship spark a series of unsettling discoveries. Captain Desna and her crew quickly realize they are unprepared for the revelations that lie ahead. As members of her team are affected by these mysterious events, Desna faces mounting pressure and growing fear about the fate she’s leading them toward.

Busch’s writing style is captivating, drawing readers in with vivid descriptions and a perfect blend of sci-fi, horror, and suspense. The way he builds tension is masterful—some moments left me truly unsettled, forcing me to take a break just to catch my breath. The technical aspects of the futuristic world are woven seamlessly into the plot, adding depth and excitement to the narrative. Busch's detailed explanations of the spaceship's technology were fascinating, and they enhanced the story without overwhelming it. The pacing is tight, and the sense of dread steadily escalates throughout, making it hard to put down.

One of the most striking elements of the book is how it plays with shock and horror. There’s a disturbing intensity to certain scenes that left me both riveted and unnerved. While some moments felt gory and unsettling, they served to heighten the story's tension and keep me on edge. The ending, in particular, is haunting—it left me in deep contemplation, still processing the layers of what I had just read. The characters are equally well-crafted, and Busch uses them to explore thought-provoking ethical questions, adding depth to the story's overall impact.

Cargo Hold 4 is a gripping and unsettling sci-fi thriller that blends horror and suspense with a powerful narrative. Lonnie Busch has created a world that is not only immersive but also leaves readers questioning the boundaries of science and ethics. It’s the kind of book that keeps you hooked from the first page but also lingers long after you’ve finished. I highly recommend it to fans of science fiction who enjoy a touch of horror and the thrill of exploring the unknown.

Held within a massive spaceship, millions of miles, and years away from Earth, the crew of Gretel finds they’ve excavated an organism capable of producing life. Built with forty cargo holds, Gretel’s mission is to collect samples, minerals, video, air, gas, soil, and photos to store until decades later when they return to Earth. But, just five years into their mission and cargo hold 4 is emanating banging, loud cries, moaning, and vibrations all throughout the ship. Putting it’s eight crew members to the test with little sleep and fraying nerves, Captain Desna decides something must be done.

From evasive maneuvers to space walks, tight spaces, light, and numerous other attempts to rid the ship of this unknown being, author Lonnie Busch continues to show off his stellar writing skills. Creating a mind-bending science fiction story that leaves readers examining life as we know it, “Cargo Hold 4” has us reimagining the definition of stowaway and the consequences we all face.

Stuck amidst the confines of this massive spaceship, with just eight crew members, some out of commission due to illness and unknown catatonia, each with a different area of specialization and function aboard Gretel, Busch redefines the genre of locked room thrillers. With no connection to the outside world, Captain Desna, First Mate Berlin, and various other members of the team must decide how flexible our morals and ethics become when dealing with the unknown.

“Cargo Hold 4” is out of this world, and still making readers ponder all we think we know. Lonnie Busch captivates once again with his imaginative plots, relatable themes, and interesting characters.

I love books like this. For almost the entire book I had no idea where it was heading but the ride was great. Interesting characters that actually seem like real people. A fascinating seeing. The whole thing reads like a (pretty freaky) movie, it's that easy to imagine everything due to the clarity of the author's descriptions.
The ending was both surprising and the obvious destination...but only in hindsight. I finished several days ago and elements are still playing on my mind. That's the sign of an engaging book in my opinion.
I enjoyed this so much I moved straight onto another of the author's book ("All hope of becoming human") and that's, if anything, even better.
Needless to say, I've found another author with a back catalogue to plough through.

Revolving around the classic case of a mysterious stowaway in a cargo hold during a decades-long space exploration, the crew aboard the vessel are pitted against unfathomable odds. Personalities spark and tempers flare, and soon, all-consuming despair threatens to doom everyone as fear clutches them all. Lonnie Busch once again conjures a character-driven tale, delving into the psyche of each while spinning a convincing, terrifying plot that keeps you guessing. Pushing the unsurmountable odds aside, the crew resolve to work together to rid themselves of a nightmare. This book was riveting! A slow-burn nightmare unfolding, testing the moral fibres of humanity, right to the terrifying end.

Cargo Hold 4 by Lonnie Busch – what can I say? This is sci-fi at its best – gripping, imaginative, strong characters, space, aliens, danger… it’s got the lot!

The premise is as follows: a small crew on a huge ship are on a mission which will outlast the lifetimes of many of those on board. Their aim is to collect samples from alien planets and store them in the ship’s huge holds. Except one of the items collected is unwanted. The tension builds and builds as the crew – led by Captain Desna – find out more and more about their stowaway in Cargo Hold 4.

I really enjoyed this book, It’s well written and has got everything I would could ask for in a cracking sci-fi.

Busch reveals the crumbling mental state of a spaceship crew under horrific conditions while ratcheting up the tension in the pressure cooker that is CARGO HOLD 4. A masterclass in suspense writing and a riveting examination of the human – or not so human - condition.
This is one of my favourite books I have read in the past few years. I am a big fan of Lonnies writing style, it is very engaging, and he really knows how to spin a yarn.
I received an ARC of this book in exchange for an honest review.

Lonnie Busch’s Cargo Hold 4 is a brilliantly executed, modern take on old school scares. In particular, it draws on elements from the classics of 1950s sci-fi horror as humanity makes their first steps to explore the galaxy. It pulls the reader into the claustrophobic paranoia faced by a close-knit crew aboard a lone spaceship on a long-distance mission, as they encounter something completely alien. As their paranoia rises, and the ship echoes with their desperation, Busch plays on the reader's emotions with succinct and deft prose. A real find, and one I wholeheartedly recommended. Superb.

The crew of a long term space exploration vessel have their dynamics all worked out, until banging echoes from Cargo Hold 4. Thus the nightmare begins...

I read this one in just over a day as the narrative ramped up, employing a few beloved thriller sci fi staples along the way. But it was those aforementioned character dynamics that sang out here. As the stress grinds them down, true nature appears, like a space bound Lord of the Flies, and humanity becomes its own worst enemy.

Wonderful, affecting, chilling and thought provoking.

Audiobook: I was entertained by this story. As the story unfolded, I started to feel like I was living with the scientists on the spaceship. In my opinion, the story was thought-provoking as I wondered what I would have done if I had actually been there with the scientists facing the issues that these characters were. I liked all the twists and turns. I thought Patricia Shade's narration was entertaining. I was given a copy of the audiobook. I volunteered, without financial gain, to post this review which reflected my honest opinions regarding this audiobook.

What a hold on to your chair ride, for this book. Twists and turns in every chapter. Great tension building all the way to the epilogue. One of those books you don’t want to end.

This was a decent story. Not a terribly original idea but I liked the characters, there were a few twists to keep it interesting and the ending was cool.

This book suffers from the same problem that so many horror novels do these days: the characters are so one-dimensional that the reader doesn't "feel" what they're experiencing. A DNF for me.
