Baptism of Fire (Polish original title: Chrzest ognia) is the third novel in the Witcher Saga written by Polish fantasy writer Andrzej Sapkowski, first published in 1996 in Polish and in English in 2014. It is a sequel to the second Witcher novel Time of Contempt (Czas pogardy) and is followed by The Tower of the Swallow (Wieża Jaskółki).
In the aftermath of the Thanedd incident, war is still raging between Nilfgaard and the Northern Kingdoms. The elf sorceress Francesca Findabair has been installed by Nilfgaardian Emperor Emhyr as client queen of Dol Blathanna. In exchange for her throne, however, she is obliged to withhold aid from the elven Scoia'tael commandos, who supported Nilfgaard's initial advance into the North, but now find themselves alone and unsupported as the Northern Kingdoms retaliate.
