Cloe and Elizabeth Yetti are antisocial, semi-homicidal, eighteen-year-old twins casually surviving the AI apocalypse. For the past 10 years, civilization has consisted of mindless addicts of a superdrug that machine intelligence controls from their treatment centers in drone-dominated cities. Thanks to their super scientist/survivalist mom, the twins are surviving in the forests in Northern California, until a mysterious stranger and a demonic woodland creature appear to threaten their family. They’re drawn back to a disintegrating, drug addled San Francisco to face the threat head on, armed with only a knife, a hunting rifle, and their cryptophasic twin language—which makes them immune to being controlled through “normal” communication channels. The girls maintain their grimly determined humor as they shift from just surviving the apocalypse to kicking its butt.
