Battle of the Linguist Mages

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!
