This book is a Warhammer 40,000 novel by Nate Crowley, following the mysterious and epic biography of that most supreme of all orkish warlords, Ghazghkull Mag Uruk Thraka - whose story is finally able to be told to humanity in something like its fulness for the first time since their banner-bearer, a gretchen called Makari, is captured and questioned by the Inquisition.
As you'd expect of a novel with orks at the heart (cf. Brutal Kunnin), this is a hilarious and thoroughly violent read; but as a window in the subjectivities of an orkish life, their culture, their worship of Gork and Mork, their secret shames and highest hopes, this is a true gem of a book that gives real tangible complex personality to the funniest faction in the fictional universe. Ghazghkull, from their brain trauma* to their triumphs in battle,** is as complexly sketched as the best human characters from Dan Abnett's Gaunt's Ghosts series - only as an ork. With ork shames and ork hopes, ork wiles, ork vices and virtues. I would be genuinely shocked if the Black Library ever managed to release another book that does as much for the exploration of orkish psychology as this one does. And yet it is more than a character study, for Ghazghkull's life has ramifications that reverberate across the galaxy in the mighty WAAAGH of which they is prophet and leader - all of which is to say, this story isn't over.
For fans of 40k, this is highly recommended; especially for ork players, this is a must-read. Enjoyers of tongue-in-cheek science fiction more generally will find a lot to love here too.
* As a young ork they was horribly injured, losing most of their upper skull, but they managed to hold their own brains in while for several days trekking across hostile wilderness until they found a doctor who could staple them back together and put a plate over the gap to keep the grey matter inside. However injurious though, this near-braining is credited with what gives Thraka such an intimate and demonstrable understanding of the will and ways of Gork and Mork - it is their pain that made them the prophet.
* Except against their "favourite enemy", Commissar Yarrick, who they never quite managed to defeat and so came to respect deeply - insofar as an ork can respect a human.
