It was believed that all demons were exterminated, since their blood was the only means that could destroy the immortal god. But still some survived. And they even gave birth. In the city of Shadow, under the World Tree, there lives a blind girl, Orri, who is able to see magic and draw magical pictures - portals to other worlds. One day she meets a half-dead stranger who glows with magic and gives him shelter. A good deed leads to disaster - Orry finds himself at the heart of a monstrous conspiracy. Someone is killing the gods, leaving their mutilated bodies on the streets, and the angry Nahadoth, the Night Master, threatens to destroy the entire city if the killer is not found within a month.
