"This is a stand-alone novel with material enough for six... By the halfway point, it had blown my mind twice... an audacious, genre-bending whirlwind." -New York Times

"It reads like Snow Crash had a dance-off with Gideon the Ninth, in a world where language isn't a virus from outer space, it's a goddamn alien invasion." -Charles Stross

In modern day Los Angeles, a shadowy faction led by the Governor of California develops the arcane art of combat linguistics, planting the seeds of a future totalitarian empire.

Isobel is the Queen of the medieval rave-themed VR game Sparkle Dungeon. Her prowess in the game makes her an ideal candidate to learn the secrets of "power morphemes"-unnaturally dense units of meaning that warp perception when skilfully pronounced.

But Isobel's reputation makes her the target of a strange resistance movement led by spellcasting anarchists, who may be the only thing stopping the cabal from toppling California over the edge of a terrible transformation, with forty million lives at stake.

Time is short for Isobel to level up and choose a side-because the cabal has attracted much bigger and weirder enemies than the anarchist resistance, emerging from dark and vicious dimensions of reality and heading straight for planet Earth!
