"IAIN ROB WRIGHT SCARES THE HELL OUT OF ME!" - JA Konrath
Something deadly has been born...

When pest controllers Nick Grieves and Samantha Grieves are called to a sleepy dockyard in the dead of night, they are expecting a rat infestation or an unclaimed exotic pet.

As a terrifying crisis spreads throughout the UK, a small band of survivors must fight not only to stay alive, but to prevent the country from being consumed by an eight-legged apocalypse. Not everyone is going to make it, but being human means refusing to give up—even when you're outnumbered ten-thousand to one.

THIS BOOK IS A STANDALONE ENTRY IN THE 'CURSED MANUSCRIPTS' SHARED UNIVERSE.

On January 21, 2012, according to the Mayan Calendar, the world was supposed to end. It didn't. But on that day, 113 mysterious manuscripts were discovered around the world, each one written in blood by an unknown author. After several dozen unexplained deaths befell the finders of said manuscripts, a decision was made to lock them up for good in a secret vault beneath the Vatican. It is said that anyone who reads the stories will die, and as such they are now referred to as 'The Cursed Manuscripts.'

In December 2020, new manuscripts started turning up around the world. 'Bad luck' was one of them.

MANUSCRIPT 8/24-08 (BAD LUCK).
Details below.

Manuscript 8.24-08, discovered January 2018 in Bolivia by rural pig farmer, Inti Torres Varguez, who found it half buried in the soil. Somehow the written pages were miraculously okay, but eight days later Inti was found trampled to death by his livestock and half-eaten by swarming insects. The following text was was written in a notebook beneath his bed, which is strange as Inti was unable to read and write.WHAT READERS ARE SAYING★★★★★ "One of Britain’s brightest talents."

Finally building the bigger picture.

This was another great entry into the Cursed Manuscripts series. Always love giant insects plaguing mankind and the best creeper is the spider. Looking forward to what Iain is building with these and how it will all tie together. At least we have a villain now.

Not a bad effort at a mutant killer spider read that is clearly part of a wider narrative (hence The Cursed Manuscripts #9), but can be read without having consumed the previous eight entries.

There are a couple of ludicrous suspensions of disbelief that are required, but there are also a couple of truly horrifying scenes that my arachnophobic ass could barely tolerate. Characterisations are fine, even if there is really only one who goes through a discernible arc.

So that all equates to a solid 3-star read.

Arachnophobia!

A shipping container arrives at a small North Eastern dock.
It is damaged and leaking a viscous liquid. Strange moans are heard and so the dock workers open it. It was the last thing they would do.
Police find a dead spider inside the container. A huge dead spider. It's impossible.
Iain writes another masterpiece reminiscent of James Herbert's The Rats.
A great read that keeps you hooked.

What's that crawling up my leg....

Crawlers, one of the Cursed Manuscripts by Iian Rob Wright, is about genetically modified spiders which, once they escape, wreak havoc and rack up a big body count wherever they go. The writing is of the highest caliber, with flawed and believable characters who sacrifice themselves to save others, realistic dialogue, exactly the kind of expletive laden dialog one would expect during a giant arachnid attack, good plot, fast pacing and very vivid descriptions of the results of said attacks. This is a highly enjoyable read, unless, of course, you're an arachnophobe! 5/5 stars, highly recommended for horror fans!

nightmares

I should not have read this before bed. It seems like the wait for a new book takes forever, then I get greedy and read the whole thing in one sitting. This one was really good. As are all of them in this series. Now I have to go read something light and fluffy so I can sleep eventually.

Yucky

Yucky but scary of a different kind. Giant spiders not my cup of tea but still read it like a fool now I'll probably have nightmares.

I am a sucker for spider-related books, whether it’s horror, or… well, it’s usually horror. I grew up loving spiders - I’d catch and feed them grasshoppers in mason jars in my basement, and these days I invite spiders to come and threaten the other cryptids that live in my house. I’d also read Iain’s previous book, The Spread (Book 1: The Hill), back in 2021 and remember really enjoying it. (It’s memorable, if not especially great, bright green cover helped.) So when I saw Crawlers creep up on Kindle Unlimited, I pounced.

It’s a pulpy, squishy, at times really silly blast. There are thousands of little spiders, a handful of big ones, and a group of hapless heroes that would feel right at home in Arachnophobia (The movie, not the overall fear…). I was surprised when I saw the page count because it felt like a snappier, shorter novella when I was reading it. Like Wright’s previous book, I was reminded not to get attached to anyone in Crawlers - no one is safe from his keyboard.

There are a lot of questions revolving around some of the characters’ logic in this book, from tractors, to dissolving protective gear, to ignoring medical warning signs, to going to a general practitioner when you have a specialist on call, but it all fits the overall B-Movie vibe of the book.

My only real complaint is that when I picked it up on Kindle, it was not designated as part of a series, and it is - it’s book NINE in his Cursed Manuscripts series. This meant there were several characters and references that felt like I should know who they were, or care about their inclusion, and I didn’t. Plus and Minus for me there, as I now have eight other (presumably) deleriously delicious horror/thrillers to read, but it also made this book, which would have stood on its own eight legs just fine, weaker because of it.

Still - it was a lot of fun, and it’s spiders killing people - what’s not to love?

(I need to get my hands on some of the special edition paperbacks Wright sells on his website - they look rad.)

Wow!

Crawlers by Iain Rob Wright makes it clear that the author put real effort into researching spiders and insects. You can feel it in the details. The way he combines different species to create his terrifying arachnids is both fascinating and unsettling, and for such a short book, the amount of research behind it really stands out. I wouldn’t be surprised if he draws on this groundwork again in future stories.

The characters who get caught up in the chaos are only briefly sketched, yet they still manage to feel sympathetic. I think that has a lot to do with the universal squeamishness many of us have around spiders. When you imagine not just a handful, but thousands, maybe even millions of them, it is easy to connect with the fear these characters face. The small group at the center of the story, including a self‑proclaimed pest controller, an arachnologist, and two investigative reporters, quickly realize that the danger reaches far beyond their own survival.

Some readers might hesitate because of the subject matter, but I found the book absolutely worth diving into. It kept me awake longer than I planned, and honestly, that is part of why I recommend it. It delivers exactly the kind of creepy, fast‑paced experience you hope for when you pick up a creature‑feature thriller.

If you don’t like spiders even a teeny bit don’t read this.
Excellent addition to the cursed manuscripts by Iain Rob Wright.
A scary time as a huge spider is transported in illegally and then releases mayhem.
I’m not a fan of these creatures, but I had to read this as I’ve read the rest in the series and they can be linked and cleverly if not sneakily get brought into each other. Not always, but usually, ok often. I love this series though. Quicker reads but nothing less for that.

Gripping as always

I've read all of the Cursed Manuscripts released so far, and found myself hooked within the first couple of chapters and can't put them down. This one was no exception and I finished it within a couple of days. They can be read as stand alone books but there are nods and Easter eggs from other books worked in, which I love. The only problem is waiting for the next one in the series to come out.

Another masterpiece

Brilliant story which brings back some well loved characters, as well as introducing new, interesting ones. The creatures were scary without being made into the villain, which is quite the feat. I also appreciate the nod to HD, as this is a condition that very few people know about and needs to be discussed more. I was pleasantly surprised to see it mentioned. Another masterpiece by a very talented writer. I look forward to the next one.

I don't know where to begin with this review. The story had some exciting parts and was well written. However, in my mind I was always waiting for something to happen, although I don't know what. People die from these spiders. These bugs are real baddies! I would say, Give it a try - especially if you read and enjoyed any of the others in this series. I don't think I will follow through on them at this time.

Didn’t enjoy this one quite as much as I did the other cursed manuscripts books. I guess bugs don’t really hold my interest and I didn’t find it particularly scary/horrifying like some of the others. Still enjoyed it though and finished it over 3 days. And will look forward immensely to the next one.

Crawlers is a decent creature feature in which a race of genetically modified spiders get loose in Northeast England and begin killing people with their bites. Overall, it's a good if pedestrian horror novel which arguably features its "best" scene way too early in the book.

creepy crawly feeling

Great book! Loved that it did not have a happy ending. I definitely love the way they describe the female spider made it almost like a romantic thing. Definitely I'm gonna be looking in dark corners and tires from now on.
