A train ran and operated by AI where every single train car is a terrifying escape room of sorts? SCARY! I’m obsessed with this series! Ander and Liam are some of my favorite characters and I’m so attached to them at this point it’s not even funny! I love the dialogue and banter throughout. Even with everything going on. Each train car was absolutely horrifying and the deaths in this one were pretty brutal! Each book in this series just keeps getting better and better I swear!

Love this series but hoowee! Make sure you check your trigger warnings with this one. Several sensitive topics and so. much. gore
I love the progression and getting more insight into the bigger picture. I couldn't wait for this installment, and it did not disappoint. Looking forward to the next chapter!

5/5⭐
I'm grateful to have recieved an eARC of this book from the author and this is my honest review.
I don't even know where to start honestly. I'm getting more obssessed with this series the more I read and I never want it to end, because Ander and Liam are now my comfort characters.
What makes it special and unique to me are the different settings in each book. The story stays fresh and fun this way. Moving train was a great set up for a slasher and I loved the idea of each room being set up as an escape room. I was amazed at how many different scenarios we went through and it never got boring. My favourite though is still the underwater facility.
At first I was really missing Liam, because I loved his and Ander's interactions in previous books. Also he's just an amazing character. But the more I read the more interesting it was to watch Ander figure things out by himself and see him grow as an individual. We also got to know more lore about Ander's family/ancestors which I really enjoyed. Overall we had very diverse set of characters and I loved all the representation we got. Apart from Ander I had at least two characters that I really liked and had my fingers crossed that they both survived (didn't happen). One of them did in fact die and what made their death even more sad (yes i cried) was the fact that they were very likeable and kind and their personality was built up really well, which made their death very emotional (just like a certain character's death in Blood in the Water, which also made me sob).
The plot was fairly fast-paced and the tension in the beginning was good. The first deaths were already brutal and left me with my mouth open and a little sick to my stomach (but like in a good way. i think). And then it just kept going and going. What really threw me off was the plot twist towards the end. Really didn't expect that, but found it brilliant. And finally at the end we got to see Liam and Ander together which left me with a smile on my face after the entire horrifying ride. Hopefully we'll have more of that in the next book.
Very gory and fun! I can't wait to see what the author comes up with next. I'm going to be (im)patiently waiting until then.

Oh my fucking god is it 2027 yet??? I need to get the next book in my hands now. I was so excited to find this on kindle unlimited I spent a good part of my friend bachelorette\ bachelor parts reading this.
I absolutely love Ander and Liam. While you don't get a lot of Liam you do meet such an interesting cast of characters on this insane train escape room from hell. With this there was no holding back, and you learn more about the lore of the crystals which has been on my mind for months. And let's talk about the premise of having to solve escape rooms in each train car to try to survive. Of course I have the characters I became extremely attached to crossing my fingers with every car game hoping they don't die. but Argh now I have more questions that are going to be bugging me until the next book!!!!! This has become one of my favorite series!

The books in this series genuinely just keep getting better and better! I loved the mystery/thriller vibes of this and how things came together in the end. The casual queer representation was also amazing to see in this genre especially. The escape room vibes was amazingly done, it had good tension that left me wanting to read just one more chapter… and then another.
The concept of AI taking over something and it not going well (shocking no one but the rich) was a horror on its own. Honestly, this book really felt like it had Saw vibes to it as the characters fought to stay alive in escape rooms from their nightmares. I really liked the pacing of this book, while it was longer I enjoyed how detailed and descriptive it was.
Ander is just out there living one nightmare after another. Ryan was such a cool new character, at first I wasn’t sure about her but happy to say my opinion changed so quickly. She is such a badass. Also loved seeing more of aunt Carole.
I am really looking forward to seeing what horrors the next book will hold.

Thank you Matthew Corr for this eARC, these opinions are my own. Ok this series just keeps getting better and better! Ander has suffered through three massacres already and he just wants a chance to spend a normal weekend with his boyfriend Liam. But Liam’s on the other side of the country at college so Anderson has to get there first. Luckily Seth Bastian, a tech-billionaire, built a AI-powered cross country train that will have Ander to Liam in 12 hours. Ander is among one of the first to ride in the Horizon. Joined by an assortment of others they’ll get to be the first to discover the luxury of this new form of travel. Only as typical in Ander’s life things don’t go as planned. Soon the passengers are fighting their way through a series of escape room like train cars, each more deadly than the last. One thing is for certain not everyone will survive. But has Ander finally reached his end? So the gore in this series just keeps ramping up! This one was seriously gorey and blood with some absolutely shuttering deaths! I think in terms of non-Ander characters this one was also the hardest for me because I wanted so many of them to live, but in typical slasher fashion they do not! For this one definitely think of Escape Rooms (both the games but the movie as well) mixed with the blood, guts, and messed up ness of the Saw movies! Plus we are starting to get a better picture of the mystery behind the crystals and how it connects to Ander and his dad! Horror lovers will love this one! Can’t wait for book 5!

This is the fourth book in the Slasherverse series, and after every single one, I ask myself the same question: "How is Matt going to top this?" Somehow... he does. Every time.
It has very quickly become my favourite book of the year so far, and honestly, it's by a lot. (Please don't tell Matt. I refuse to be responsible for that ego.)
At this point, Ander deserves compensation, paid leave, and several years of therapy. After surviving the first three books, you'd think life would finally cut him a break. Absolutely not. Instead, he's thrown headfirst into yet another impossible, life-or-death nightmare that had me constantly asking, "How on earth is he getting out of this one?"
The answer? The same way he always does... by the skin of his teeth, a ridiculous amount of determination, and what can only be described as supernatural levels of dumb luck.
This book put me through every emotion imaginable. I gasped. I laughed. I cried. I threatened to throw my Kindle across the room. I called Matt a few names... apologised... then immediately started repeated them a few chapters later.
The setting was such a brilliant idea. A horror set aboard a luxury tech train sounded fun, but I genuinely wondered how much chaos could actually happen on a train. Turns out... A LOT.
I don't want to say too much and spoil anything because this story deserves to blindside you the way it blindsided me. This was an absolutely bloody brilliant read.
If you've been following the Slasherverse, this is an absolute must-read. And if you haven't started the series yet...

Thank you to the author for this free digital ARC read in exchange for my honest review of Terrorbyte Express.
This is the fourth book in the Slasherverse series and it does not disappoint. It's a fun and killer read. In this one we end up with a killer that is stalking all of the characters on a tense, deadly train ride. Will Ander be able to make it to Liam this time? To find out make sure to read this one! The author wrote this well and I liked every character in it. Every death is definitely brutal and the tension is high at times that it had me on the edge of my seat the entire time. I look forward to reading the next book in this series. Overall, I did enjoy this one and would recommend it to any reader who loves horror books.

The best one yet! The setting of this book allowed for an anything goes vibe and honestly every chapter was so fun and engaging. I’m lucky enough that I was able to binge all four of these books at once, how am I supposed to wait until 2027 for book 5?!
