Ghazghkull has set his sights on the Blood Axe world of Gabal for a titanic showdown with the Black Templars, and not all of his boyz are happy about it.

[Warboss Mad Sam · Rating 5 out of 5]

I am avoiding as many spoilers as I can in this review, because I want people to read it and be inspired to read this book in entirety.

READ.THE.EPILOGUE. I know some readers skip that. Don't.

Denny Flowers absolutely killed it with this book. Ghazghkull Thraka: Warlord of Warlords takes place on Gabal, who has fallen far from imperial influence for centuries.

Claimed by the Blood Axes, the grand warlord decides to depend upon this planet and truly claim it- as he does not approve of blood axe methods. (naturally, as a Goff raised ork)

This book is primarily about Blood Axes and Black Templars, with many POV shifts that are easy to follow. (a lot of authors do this wrong, Denny does NOT!)

You're going to love Slitta, and youre going to be inspired by Ghazghkull more than ever.

Several great quotes that I have marked to share later from this book.

This book takes place after Grotsnik- Da Mad Dok. There is a brief mention of a scene from that book, so we know where it is on the timeline. After the most recent fight on Armageddon.

This is a book I did not want to put down!

Another interesting ork novel showing more intrigue, nuance, and depth to the orks of the Warhammer universe. It's a very cool story and it sort of acts like a sequel to Grotsnik, but not in a way that you need to read Grotsnik to understand what's going on. I really love the ork novels and this one shows another side of ork society that I feel hasn't been explored in depth, that of that every boss needs to keep an eye out for someone to supplant him, even the biggest, baddest boss of them all.

This is the opposite of the general critique of Black Library novels, and frankly it’s the better option for the book, but there’s some really interesting ideas here and compelling reading, that’s undercut by the action being…pretty underwhelming. The plot also suffers in that it’s just very hard to write a particularly compelling plot about an assassination plot that, by the nature of the setting (or history, for historical fiction), the reader knows *cannot* succeed. And I don’t think that Flowers quite pulls it off here. But he earns a lot of goodwill in the way he writes his characters, who are almost uniformly compelling. I absolutely love the feudal world to whom the Imperium is a legend of the distant past, with historians trying to interpret space marines through the lens of myth, being reclaimed by the Black Templars, who bring more ruin to this world than the Orks do. Frankly it was so interesting I wish I got full length treatment in its own book rather than be relegated to a subplot in this one. I do also appreciate the way the book looks at the question of not, who is Ghazghkull Thraka, but what does he mean to the Orks? To Mad Dok Grotsnik? To his enemies? And I think those two threads elevate the book to be one I generally enjoyed, even though the main plot didn’t really grab me.

Da Warlord of Warlords returns! I absolutely love Ghazghkull, but having recently read the Grotsnik novel I was cautiously optimistic. Mind you, Grotsnik was not a bad book, it just wasn’t what I expected at all. That said, Denny Flowers did a great job on this one. It was so good it even made me like/apreciate the Grotsnik book more! The contrast with the humie ‘ard gits (black templars) made the orks stand out in a great way. And because of this, the way the orks sound smart when talking amongst each other made sense, since from the ‘umie perspective they still sounded like drunken hooligans. My only gripe with this book is the same I have with every Ghazghkull story: I want more Ghazghkull. I you like Orks you’re gonna love this book!

"For you the day Ghazghkull krumped ya mates on Armageddon was the most important day of your life. But for me, it was Tuesday".

Orky goodness.

I have never before bought a special edition of a book without having read it first. I was just a little hesitant about doing so, because of the obvious question: What if it sucks balls? However, I'd read Denny Flower's Grotsnik novel last year and had a thoroughly good time so I decided to risk it, and man am I glad I did.
This, I think, is now my favourite Warhammer novel. Not just 40k but Warhammer in general. I am of course more than a little partial to orks, and on top of that I am of course even more than more than a little partial to Ghazghkull Mag Uruk Thraka. But hey, this was just wonderfully written on top of being my #SpecialInterest. Every character, every choice and every fun little moment is particularly chosen and crafted in order to bring the fun and joyful bleakness out of the setting. Other authors have pitted more serious factions against orks in the past just for the contrast, Mike Brooks flicking between terrified humans and giggling orks in the novel 'Warboss' comes to mind, but Denny Flowers does something here that I am struggling to describe. He makes the differences feel sewn in to the universe in a way that is entirely natural. He makes the comic relief of the orks feel meant to be, rather than an insert. These orks are 100% diegetic, brutal, silly, GREEN.
There are, of course, fun nods to the reader still. The Black (Knight) Templar losing an arm and declaring it is 'but a flesh wound'. Or the double entendre of the orks calling the Templars 'cross gitz', not just because they wear the cross but because they are generally quite cross in any given scenario. I found myself giggling a fair amount.
The development of Ghazghkull as a character in the current setting of 40k is what I had been craving though. He's always just been this legend, who is entirely tangible but just impossible to wrap your head around. Not enough clues, even in Nate Crowley's wonderful 'Prophet of the Waaagh!', which was more of an origin story rather than a current Ghaz. But Flowers delivers in the perfect way on this front. I came out of this book still unsure exactly of how Ghazghkull works, but now I've seen him, current, massive, unstoppable. He's interacting with his Waaagh! Interacting with other factions. Talking to Templars nonchalantly about the general workings of the universe in his completely fluent High Gothic. It reminded me why he's my favourite mushroom while also delivering so much more on his motivations, thought-processes and general being, chapter after chapter. I truly didn't want this one to end.
I am very excited for Denny Flowers' next output, and I hope it is ork related. Not just that, I hope it is Ghazghkull/ Grotsnik related. Just do more. Give me more.

Without a shadow (boss) of a doubt one of my favourite 40k books of recent years. Numerous times it had me guessing, had me ponder, and had my cheeks aching from the smiles (and laughter) of Orks just being Orks. I'd heartily recommend it to anyone who likes 40k, and call it utterly essential reading for Ork fans.

As an aside, I listened to the audiobook while reading the book book and it must be said, Harry Myers' performance is out-zogging-standing. I may go back and listen to the whole audiobook now instead of just while busy working and painting.

The Imperium are there and they have their bits of time in the sun, but it really is the Orks and their shenanigans which are the shining cornerstone of this book.

10/10 would krump again.

perfect time for a new ghaz/ork novel as i go through my armageddon catch up :)

boy oh boy was this a lot of fun!! denny flowers captures orks perfectly. these chaotic and cunnin’ boyz were awesome.
and for how much this novel has going on, it’s so well balanced between all the povs!
the characters all have such a unique presence to each of them, that i found myself getting excited when either the orks, the humies or the space marines were the focus of the chapter.

since this being brand new i will avoid any spoilers but i highly recommend people give this a read!!
we have an early contender for 40k book of the year already.

[Maksim Atanasov · Rating 5 out of 5]

A pretty great Ork book. Really enjoyed the story and the ending leaves you wanting to know more of what happens with Gabal (the world where the story takes place). The character development of Ghaz is also satisfying.
The only thing I did not like is that the orks speak in normal English rather than Mike Brooks' ork accent.

[Tom · Rating 5 out of 5]

Easily the best book to come out of Black Library for over a decade! The authors ability to portray an alien race so perfectly, but to intermingle that with human and post human characters is divine. A must read for all 40k fans.

[Tyler · Rating 4 out of 5]

3.5. fun book and well written. It's always a pleasure to read about the grand warlord himself and other Ork shenanigans but did we really need all of those POV's? It felt very crowded, too crowded actually. A lot of the plot points just felt like they weren't needed.

[Jesse Swink · Rating 4 out of 5]

Good but not enough Ghazghkull in my opinion.

[Swalah A · Rating 4 out of 5]

good book. would have been funny if the citizens of Gabal called the God Emperor the God-king since they were all medieval but...the black templars did come to them so it wouldn't have ended well
