Book excerpt: Five years ago the monstrous god Cthulhu awoke from his slumber under the sea, sending most of the world into madness. In the aftermath, terrifying creatures entered our world, a cult of human-sacrificing Cthulhu worshippers emerged, and humanity has struggled desperately to survive. Saeko, Dell, and Kelsea are three such survivors, who have lived in the underground bunker of Arkham since age 14.
