This book describes Death as a bloodlust, which EXACTLY THE OPPOSITE we see in the game and comic books.
We see unneeded carnage, too much conversations, since we know fourth Horseman as a silent one. Guts, blood, gore, made up moments and lack of empathy with him.
In game Death is "accused" for being not such a bad man, he saves multiple characters, offers salvation to a lost soul. He slaughters a lot, but only those who stand on his way.
SPOILER!!! SPOILER!!! SPOILER!!! In book, sending Balisatra to exile, mocking on Hadrimon's fate, ... Is author making fun of us or I missed something through the story? I couldn't accept that, after all I saw, after the games and the dialogues and the whole story where Death is actually not such a badass, this end just didn't fit. None of the story fits. Death in this book and Death in Darksiders series are not the same personalities. This comes from person played the game 20 times and memorized every word, every sight, every detail of Horseman's character.
I also can say manner of writing is kinda chaotic. Too similar sentences, too long descriptions of battles and things that are not so important, and at the same time not enough details of actually stuff.
It's all so rotten, so disgusting, such a lack of aesthetic. In games we have both good and bad, all we have here is guts and corpses.
There are absolutely nailing parts, like the never ending fights between War and Death. And such that could drive you crazy with their slow motion. Really, when you are awaken from death the last thing to explain would be how you crash trees. Death asked angel what happened and we read a few pages for nature with the same words over and over again. Sloppy.
In game Death is with his mask while fighting Nephilim, in book he puts on a mask to apart his past from his present. In game Death bleeds, in book it says he can be wounded but he doesn't shed bloods.
In comics War is speaking open to Lilith, even treating her, in book War is forbidden to meet Lilith not to fall under her influence...
If you are going to be a fan and write about someone else's character, first learn everything about him! Loud words are not gonna help you here.
AND... Death is not a savage, some moments makes those who read being disgusted. In original version he helps others, spare things that are asking to be slayed, in book - not so realistic I have to say, he shows no mercy, a whole new different character that is not Death. Good fan fiction, but not good enough to be perfect. If it was me, I would write it other way. Better way.
