So many things to say about this book.
First, I would like to mention my history with the Horus Heresy Novels. I was a big fan of the first 5, especially Fulgrim. I had no interest in reading it, based on previous depiction of the Emperor Children's, and Graham McNeil story won me over. After that, it's been a long and painful journey for me. From "Descent of angels" to "Tales of Heresy" I went from "disappointed" to "giving up" on the Horus Heresy. I stopped reading these for a few months, until I came across a cheap copy (I kidd you not. I bought a GW product cheap) of "A thousand sons". this Novella was incredible, and made me realize I should not focus on the reading order since the timeline is doing so many back and forth, and just read the books about the legions and characters that interests me.
Hence why I chose Angel Exterminatus. I did not know much about the Iron warriors, and the few things I knew about Perturabo was his reputation of being the lamest Primarch. Like, all the worst human traits seemed to characterize Pert' (Yeah, after reading this novel, he's "Pert'" to me. Shut up, you don't know him like I do. He is different when his friends are not around). I owe an apology to Pert', because he is now my Favorite Primarch.
Anyway, Spoiler free review from here.
So, what to expect about angel Exterminatus ? First, it should be known that the iron warriors are not the sole Focus of this book. The whole cast of "Fulgrim" comes back, crazier than ever. Last but not least, a ragtag crew of Iron hands, accompanied by a lonely Raven guard and a Salamander Apothecary right out of Isstvan V plays the role of troublemakers in this story. The story shifts frequently between their point of views, offering a lot of diversity to the story.
Despite the large cast, the star of the Story is Pert'. He is depicted as a very flawed individual, with a near limitless potential hindered only by his character. Because Pert' is needy, jealous, and overall frustrated to never have been recognized as the equal of his brothers. His sole reason for siding with Horus is the feeling of acceptance and forgiveness he found with him. This fact is brought up many times during the storylines, as our primarch often wonders what could have happened if things had turned out differently. And in the middle of this mid-life crisis, while still ridden with guilt and shame about failing to defeat his nemesis (R.Dorn) during their latest confrontation, he is contacted by his brother Fulgrim to go on a quest to redeem himself in the eyes of the warmaster.
Let's be fair : Fulgrim does everything he can to steal the show here. The craziness started by the end of "Fulgrim" is now full on madness in this book, his whole legion now being corrupted and perverted to obscene levels. And even though our Iron warriors are depicted like badasses from the first page, the feeling of danger coming from the Emperor's Children is ever present. Fabius Bile, in particular, appears as a constant threat to anyone approaching him. Even by the E.C standards, Fabius represent absolute Nihilism. He does not respect anything or anyone, only his craft matter in his beady little black eyes.
Tension builds quickly between Pert' and Fulgrim, to a point where a chasm clearly appears in the traitor legions ranks : Some are still firmly anchored in the real world, still thinking about politics, conquests and such, while others are already completely lost to chaos and the warp. Between "A thousand sons", "legion" and this book, it's important to note how much these traitorous legions fall to chaos are real dramas. Space Marines are rumored to be emotionless war machines, but half of the legions would not have defected if the Emprah (blessed be his name and his ô so golden perfection) had actually paid any attention to his sons feelings.
Even though the book features plenty of actions, the best parts are actually the psychological elements involved between all characters. Pert' and Fulgrim are trying to outwit each others to trick or see through the tricks of the others (Until Pert' lose patience and just punch him a thousand times in the face), the Iron warriors leadership keeps fighting internally for a promotion (Guys, you're not getting paid, so just quit it), while the E.C tries to corrupt everything they touch with their sticky hands. They even got an Iron warrior warsmith on LSD and drunk at some point.
The only issue I had while reading this book, is that the characters from the IW and EC are so colorful that the Iron hands looks boring in comparison. Sure, their engineer almost blew up their ship twice, and the Raven guard is a cool stealthy assassin with a jet pack (Take that Bobba Fett ! Buy some huge pauldrons if you even want to compete) but most of the time their appearances felt like it stopped the story short. Like a cloud of flies swarming two titans.
Still, the last act of the story is epic, depicting one of the most important event of the Horus heresy brilliantly. Characters dies, some others evolve for better or worse, but nobody ends unscathed. And by the time you reach the last page, you want even more.
That's also a strong point of this novel. Characters have arcs. for exemple, Kroeger starts as a soldier, then a warsmith, learns his new place within his legion, and end up set up on the path of a Khornate berzerker. And that goes for most secondary characters of this novel. This might looks like something obvious, but not all novellas take the time to craft real characters and have them mature throughout the story. Especially Primarchs, whose characters seems so set in stone.
Is that too long ? I lost track. Anyway,this is definitely a must read for any 40k fan. I would only advise to read Fulgrim beforehand to fully enjoy the story and it's cast.
