The novel doesn't do a very good job fusing horror and comedy. Both exist in the book, but it feels more like there are designated horror segments and designated comedy/action segments that you whip between at the author's whim. The horror is quite evocative and enjoyable, but the bulk of the book is the action and the comedy, which is so bad it's insulting. It's not witty or clever, it's crass, violent, and gratuitously edgy, with penis and shit jokes and characters who say slurs and bad guys who punch everyone in the balls making up the bulk of the author's comedic repertoire.

If you enjoy that sort of stuff, you might find the book enjoyable. I certainly don't object to reading books with transgressive, strange, or potentially offensive material, but in this novel it feels like meaningless shock humour, edge for the sake of edge, serving no purpose other than to make you go "omg did he REALLY just say that?!?!?!?!" after the bad guy sings some pop song with the lyrics rewritten to be half racial slurs. It's an agonising read if the humour doesn't work for you, and it did not work for me at all.
