Long ago, long before Sylver the weasel was born, the humans all left Welkin. Now life for a weasel—under the heavy paw of the vicious stoat rulers—is pretty miserable (unless you happen to be a weasel who likes living in a hovel and toiling all hours for the benefit of the stoats).

It's certainly not enough for Sylver. Or for his small band of outlaws, both jacks and jills. but slingshots and darts can only do so much against heavily-armed stoats and life as an outlaw has a fairly limited future (probably a painful one, too). That's when Sylver comes up with his plan—a heroic plan that could destroy the stoats' reign of power for ever. He will find the humans, and bring them back to Welkin! And the first step is to follow up a clue from the past—a clue that lies in a place known as Thunder Oak...

I've read this book before. There's nothing like a squad of cheeky weasels going on a trip to save their island from being swallowed up by the sea. The story moves a little quickly and some of the writing is a bit simplistic for my taste, but it's jock-full of humor and heart. All in all, it's a delightful and jaunty read.

fun, and funnier than expected for a children's book. lots of loveable characters, i think children's villains get to be campy and delicious in a way that adult villains don't get to be, so i loved prince poynt and also falshead very much.

one thing i thought was cool about reading this is that it hits on a lot of why fantasy wasn't super my bag as a kid; this is a journey/adventure book, where there's a destination at the end and shit just sort of happens in the middle, which i think is common in fantasy. as a child i found the sort of random encounter format hard to follow, and i think that's still true! it's easy for me to forget what happens in this book. i see the random encounter format now as more about the richness of the world, which includes its arbitrariness as well; it's true that in life shit just sort of happens (though sometimes fantasy twists has these arbitraries end up being all connected again in a fun fable-y twist at the end; idk). in SF the novum re-organizes and re-orients the entire world towards it; so this book was an interesting experience in that there is a goal/maguffin/destination, Thunder Oak, but it doesn't drive every single scene? it's nature is occluded even up until the end.

world building was fun and weird in turns. i think by virtue of being a kids fantasy book shit just again, sort of exists. i think the inanimate objects that came to life after the humans left is my greatest source of interest, especially the scarecrows that are weird simulcra of men who feel weird about that. i think there could be something neurotic there. the position of humans in general was v unique in this book. devon called them 'ancient aliens', which i thought was cool. these beings who once existed, confirmed, and left behind all this tech, and need to be sought out again now that the tech is breaking ... idk! idk how to feel. but i think there's something v cool there.

i also think that the oppression of the weasels by the stoats leads to some interesting Moments. i was really rooting for the ingratiating weasel jester of the prince to just straight up kill him in his sleep at the end; he had these manic poisonous lines where you could tell he was kinda cracking from the strain that was neat. one of the most interesting scenes is when a weasel-friendly stoat, a noblestoat who still enjoys the labor of weasels, goes to a weasel funeral and we really feel the cultural gap despite his best intentions.

I rate Garry Kilworth highly, think him a capable and versatile storyteller, as demonstrated by such superb books as Hunter's Moon, Frost Dancers and House of Tribes, all anthropomorphic novels, but each with their own feel and style. He is fallible, though, as Midnight's Sun shows, and this book is another lesser effort, too focused on aping Redwall, and not enough on forging its own path.

It's briskly enjoyable, with imaginative ideas, some decent world-building, nice turns of phrase, and a rich vein of humour, and it avoids one of the biggest shortcomings of the Redwall books, their simplistic, black-and-white approach to the characteristics of the different animal species, always making it clear things are much more grey here. However, it's also writing down to its young target audience a bit, with familiar plotting, lightweight characters, no shortage of hand-holding, and not nearly the same vibrant energy as Jacque's books.

It honestly feels like this was written to order, for a publisher wanting a Redwall-beater, rather than something Kilworth came up with himself, and the result is something that's fast-paced fun, but frustratingly lacking in substance.

This was a bit of a nostalgia read for me, despite having never actually read this book. When I was maybe 11 or 12, I picked up the fifth book in this series (Vampire Voles) from my local library. It really stuck with me for some reason, and when I was looking to buy physical copies of old childhood favourites I decided to pick up the whole series.

Thunder Oak is the first in the Welkin Weasels series and follows the weasel Sylver and his band of outlaws. Sylver and his band live in a world where the humans have disappeared some time in the distant past, but with the flood walls of Welkin starting to fall into disrepair, Sylver believes the only way to prevent all of Welkin being flooded is to bring the humans back. So Sylver and his band set off to find Thunder Oak, which they believe holds a clue as to where the humans have gone. On the way they meet a number of interesting creatures and face a number of challenges, the primary of which is Sheriff Falshed constantly trying to apprehend them on behalf of the evil Prince Poynt.

So this book was an easy, enjoyable read. It’s aimed at a younger audience so for the most part everything is pretty surface level, but occasionally you’ll get some wild or borderline horrific scenes that you tend to find in ‘children’s books’ that were written at the start of the nineties or earlier. This includes things like . The world is fun and fantastical with some elements feeling detailed and well thought out while other things just seem to be there to be fantastical and add to the whimsy of it all. That said, the areas where this book doesn’t put its best foot forward are still nowhere near bad enough to detract from it being an overall entertaining story. I was also surprised by how funny and witty it was at points, definitely helped by the distinct characters and the way they interacted with each other.

Overall, I would recommend this book if you’re interested in stories about anthropomorphic animals and a Robin Hood type lead character and his band of outlaws going on an epic quest. It’s also a fairly easy read with short chapters and a fast pace as it jumps from one encounter to the next.

It's a nice book. Great adventure story especially for children.
Unfortunately I read this with an adults' eyes...
Definitely too simplistic and I do recall reading other more in-depth children's stories in my life.
As a children's story, there seem to be no real danger so to speak. After the first few little troubles they got into, it became obvious that all the weasels are going to have little to no consequences for anything they get into and no matter how bleak the situation was, everything felt so... light and happy... So light that even when something did happen to one of the weasel, it was like nothing. It also didn't help that Mawk betrayed the band and everyone shuns him(which is the normal reaction), then when Sylver leads them to, not just once but twice into an obvious trap, after getting away from it, everyone goes back to blindly following him like nothing happened just because he's the leader.
I also felt that, it was a little too shallow? Even as a children's story. Like I couldn't really find many moral or meaningful encounter. The story was just "there are bad stoats (and other obviously bad characters) and good weasels win every time. Let's go get the humans. The end"

Anyway! Enough of the negatives.
The story was well written. The characters were individualized and all seemed special in their own way. Descriptions of everything was great and animals were used well.

There were some odd bits that I wasn't expecting, and after having been spoiled by Redwall, I doubt I would have thought much of the style in which this tale was written even as a child. However, having read some of his other work, I know Garry Kilworth is an able author, so I docked a star because I know he could have done better. Still, this tale was funny at times, and I'm glad I stuck with it, as even the bits I didn't like (like the statues and the heavy magic/deus ex machina) served a purpose and were actually pretty inventive. Could have done without the statues, but enjoyed additions such as Hunter's Lodge, which really are rather reminiscent of old-style tales and legends.

Overall, this book is no Redwall, and the heavy comparisons I saw between the two as a kid seriously hurt my reception to this book on finally being able to find a copy and read it as an adult. If you don't go into it with that expectation and can just enjoy it for what it is, not bad at all. Certainly there are things I would have changed had I written this book, but I enjoyed it nonetheless.

Also, Mawk is the best character, hands-down, with Scirf as a close second.

EDIT: If you haven't seen the cover of the Russian edition for this work, please do. It is amazing, and I now wish I had read this in Russian so I could have that on my shelves instead. I like the original cover, but that one is just beautiful.

I had this book and book 3 from the same series as a kid, but I only recently was able to find book 2, so I tried reading it again to see how the whole story goes (I've never read book 3). I read Thunder Oak at least twice as a kid, but I didn't remember much of what happened, other than the bridge scene. I was really looking forward to finally reading this full trilogy after 20+ years of having 2/3 of the books on my shelf.

Overall, I'm pretty disappointed with Thunder Oak and not looking forward to slogging through the next 2 books. Thankfully, the writing is simple enough that it should be a quick read.

I felt the characters are largely bland, hollow, and interchangeable (other than Scirf, he's at least fun), which made the bridge scene entirely unimpactful.

I found that each chapter was just a collection of things that happened, then get quickly resolved, and which had no impact on the next part of the story. A lot of it is mildly interesting, but ends so quickly that you didn't get enough to want a deeper dive.

As a kid, I had tried reading Redwall, but it didn't hold my attention. I agree with the cover quote of being a quicker/ slicker read than Redwall, but after re reading this book as an adult, it makes me want to revisit the Redwall series for a higher quality story.

I read these books when I was young and I'm thrilled to find them again. I'm going to wait until my niece is a bit older before passing them on, because there's a fair bit of shockingly horrifying imagery in here. Maybe that's what made it so memorable? It's been years since I first read them and it all comes flooding back.
Re-reading things from childhood is interesting. On one hand, you pick up a lot of cultural references that were previously over your head. On the other hand, you notice that the pacing of the book is a bit wonky. The weasels meander around having adventures, and then in the last few pages of the book complete the quest that they had set upon to begin with.
I'd recommend these books to people who enjoy Redwall, but want a big less pious Christianity and more themes of social inequality. Basically the books are what you get from crossing Redwall with Robin Hood.

It’s fine.

I mean, the author TELLS you everything and reads more as a list of events that happen rather than as an immersive story. I was hoping for Redwall+ but found it fell short of Jacques’ work by a long way (and I don’t consider those books perfect by any means).

The story starts in the middle of things, with the weasels already on the run for some vague world-ending reason.

The characters felt flat. I don’t know or care much about Sylver. Scirf was the best one of his bunch. The sheriff was vaguely interesting too.

Don’t bother. Read Redwall or write/daydream your own

TW: death, abuse and torture

I'm very conflicted. On the one hand it was a brisk and very easy read with some great moments. On the other, you get random, nonsensical, high fantasy out of nowhere. Why are there magic statues that walk around? Why can some characters use magic? Why is there this weird plot point of a map being imprinted on an eagle's eggshell by the mother eagle before it's even laid? So eagles have built in butt printers? It was just such a weird and random plot point.

An excellent fantasy story, though I can't imagine why civilized creatures would want humans of all beings. Why can't they fix their own sea walls? Wherever this story takes place, it isn't quite Earth, though it has lots of familiar Earth animals. I look forward to becoming acquainted with future books in the series and unraveling the mysteries of the setting!

I enjoyed the adventure. But nothing like the standard of Duncton Wood, or Watership Down. The characters move so quickly from one encounter to another, without really getting to know the characters in the tale, or understand the effects of the encounters. Seems rushed?

It is a bit simplistic for older audiences, but still a good read with likable characters. Totally not a biased review over the cheeky attitudes of the best little murdee-noodle you ever will see

In a way it's like the Chronicles of Redwall but very forward driven and not a lot of back and forth stories. Overall, a great animal adventure

I was looking for fiction books about weasels and happened to come across this on Amazon. I bout it and was very exited wen it arrived. I really wanted to like this book, I really did. But it had issues that bothered me and ruined my enjoyment.

The biggest problem for me was the characters. This book had so many main protagonist that I could not remember there names. Also the personalities themselves were so flat and some didn't even have personalitys. The leader of the group, Syver (I think that his name) was just a one dimensional Mary Sue-- In fact, he is the king of Mary Sues. Mawk (I know his name) was just a selfish asshole that didn't care wether his friends died, he just cared about his own survival, and he doesn't get any better. Also Mawk stole the stage later in the book, witch pissed me off. There is Scrif, (these names, can't remember!) he was the only interesting character: he's a redneck that seems dumb, but he's actually very smart.

As for all the others in Syver's group, I forgot there names and there personalitys (if they had any).

A book without characters is a story about people you don't care for doing things you don't care about.

There was a horrible problem with the plot. The weasels have to find the humans so they can fix the sea walls, so the old guy finds a human girls journal that has riddles and clues to were the humans are at. This is were the biggest problem starts-- we don't get to hear any of the riddles or anything, so we can't make predictions on what's going to happen it the future, witch is no fun for me. Instead of reading the riddles and trying to come up with theories ourselves, the old guy just tells the weasels to look in Thunder Oak for the first clue.

About three-fourths of the book is about the weasels getting an eggshell with a map on it. What? Shouldn't they be going too Thunder Oak? seriously, the old guy has a buttload of maps you could use. Anyway, the journey to get the eggshell is just loaded with pointless things that have nothing to do with anything, and they are quite boring. Like getting kidnaped by the hog, or getting kidnaped by the sheep.

So they get the eggshell and go to Thunder Oak and get a wood carving that is of a chipmunk sleeping in a lake (this part is very rushed in the book). They, of course, they give the carving to old guy and (without us having to use our own heads) old guy tells them the humans are sleeping on the ocean somewhere.

That's pretty much it. I wanted to like it, I wanted to give it a higher rating, but it just disappointed me. I might read the second book to see if it's any better, but I don't know.

When I picked up Thunder Oak I was expecting something similar to the Redwall series, and I was pleased to find that it was as such, and more!


The story follows several characters in the land of Welkin, an island long abandoned by humans. In their absence the animals took over and statues came to life. Sylver, a weasel, and leader of a band of outlaws, sets out on a journey to find the humans.

However, not all the animals wish for the human's return, because if such a thing were to happen, the animals would have to give up their new-found lives to live back as, well, animals. Sylver believes the humans can save Welkin from certain doom, as the sea walls are washing away and the ocean threatens to flood the island entirely. Living as animals seems like a better option than drowning. Can he and his band of outlaws find the humans, and will they be able to return and rebuild the sea walls?


Thunder Oak was a splendid read, I definitely wish I hadn't let it sit on the shelf for so long. It is a tale of adventure, mystery, magic, horror, and puzzles, with a humorous personality to it. I've already purchased books two and three that follow (and I'm eagerly waiting for them to ship) so I can continue reading about the Welkin Weasels.





You Might Like This Book If...

-Adventure / Magic / Fantasy
-You are a fan of the Redwall Series or Mistmantle Chronicles

You Might Not Like this Book If...
- Blood, death, or gore are not subjects you enjoy in reading
- You're not a fan of battles and fighting

EDIT: My second reading of this was through the audiobook now available via audible. Was lovely hearing it narrated this time around, and plan to listen to the others. Incredible voice acting for the story. Not a fan of *all* the voices but they grow on you over time.

A lovely animal fantasy story, similar basis to Brian Jacques Redwall series - a bit like a combination of Redwall and Robin Hood really.

Obviously this is targetted towards the young adult readership, but I do feel it is a little over simplified in places - such as how the sheriff is always on their tail on their quests, but when the weasels are home in half moon wood having loud celebrations, he's somehow never around hmm.

I'm also not that impressed with how rats are made out to be evil creatures as it does conform to a stereotype and may leave a lasting impression on oung children reading the book, who are already told by society at large that rats aren't nice animals. It would be nice for a book like this to paint rats in a good light.

Other than that this book was a good heart warming read.

Not a bad series, but it's frankly a rip-off of the Redwall series (cross with Sherlock Holmes) by Brian Jacques, and Brian Jacques did it better (Brian Jacques actually has a balanced cast of characters, and his main character isn't just a male Gary Stu).
Not badly written, but needs a heck of a lot more to be brilliant.

Good introduction to another land of animal conflict. The story flows through each book of the series. At first glance, Weasels are probably not an animal from which you might create a hero.

I picked up the first 3 of this series at a used bookstore while on vacation. I've never heard of them before, but I think they may be just the think to feed my childhood love of Rats of NIMH.
