Andrzej Sapkowski: The Witcher series
Geralt of Rivia is a witcher. A cunning sorcerer. A merciless assassin.
And a cold-blooded killer.
His sole purpose: to destroy the monsters that plague the world.
But not everything monstrous-looking is evil and not everything fair is good. . . and in every fairy tale there is a grain of truth.
The international hit that inspired the video game: The Witcher.
