Stregoneria - Sourcery, by Terry Pratchett (1988, UK)

Rincewind is, despite himself, taken in the middle of a new adventure, an End-Of-The-World adventure: sorcery is back in the world and this means an epic magic war, Ice Giants' return, the end of everything. He's with Conina, the beautiful fatal warrior daughter of Cohen, and peculiar characters picked up on the run. The Sorcerer, Coin, is only a boy, but he's guided by his cruel father, living in his stick. Fun.
