About the book: year / "My name is the Slider, and you will find out why... before this story about me is over." The one who slides is not a person. Far from the Witcher, the protector of the County, he hunts people, sneaking into their houses to drink blood while they sleep... When a local farmer dies, it is natural that the Slither will want to feast on the blood of his beautiful daughters. But the farmer offers him a deal: in exchange for Slither delivering his younger daughters to safety, he can take his eldest daughter, Nessa, to do whatever he wants with her... Slither's promise turns into a treacherous journey for him and Nessa, where enemies wait at every turn. Enemies, including Grimalkin, a terrible witch killer, are still searching for a way to destroy the Devil forever. The new installment in The Witcher's Apprentice series introduces the Slither, one of the most terrifying creatures created by Joseph Delaney.
