This is book number 4 in the Witcher series.
The witcher returns in this sequel to Blood of Elves, in the series that inspired The Witcher video games.
Geralt is a witcher-guardian of the innocent, protector of those in need, and in dark times a defender 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.
