The Time of Contempt. Andrzej Sapkowski

Geralt is a witcher: guardian of the innocent; protector of those in need; a defender, in dark times, against some of the most frightening creatures of myth and legend. His task now is to protect Ciri. A child of prophecy, she will have the power to change the world for good or for ill - but only if she lives to use it. A coup threatens the Wizard's Guild. War breaks out across the lands. A serious injury leaves Geralt fighting for his life.... And Ciri, in whose hands the world's fate rests, has vanished....
