2.5 stars. John Birmingham returns to the world of Dave Hooper, exploring what would happen if a working class Trump voter got superpowers, and a invasion of demons from the underworld with apon which to expend them.
The tale picks up right after the conclusion of volume #2, with Dave and Russian spy Karin Varatchevsky calling a truce on account of the problem that what with their super strength and all, they cannot kill or subdue each other, so they might as well join forces against the monsters. And in any case, they both think that Trinder, the MIB who is out to capture Karin is an arsehole.
Birmingham has introduced some necessary tweaks to the powers of both the monsters and the superheroes. First, the introduction of 'Threshrendum' a species of empath demons which can interdict Dave's enhanced speed (which tended to make him invincible, and the demon fights a dull turkeyshoot), making for a more even contest. And secondly, the ability of some of these empath demons to dine on the brains of captured humans, thereby gaining their knowledge and strategy. in a stroke of luck, one such demon chowed down on strategist Compton's grey matter (in addition to that of random other morons and military personnel, making for conflict in the resultant hybrid demon Compt'n ur Threshrend's addled brainpan), with the effect that thedemon hordes can use modern military planning and learn from their mistakes, rather than repeat them, like dumb nazis from any number of WW2 movies.
The story moves along mostly with verve and humourous snark, despite getting bogged down in some overlong gory moster battles. Through the agency of the very kick-ass karin, glimmers of civilization gradually penetrate Dave's thick scull (making him a most atypical Trump voter, it must be acknowledged), and it is these converations and interactions that are the most enjoyable passages of the book, together with our plucky little demon empath's fevered internal monologues. Will Threshy find tru love, will he even survive?
The book ends on another cliffhanger, so there is some chance of Dave reappearing in future if the fancy takes. Not sure I'd bother, unless the library happens on a copy.
