Andrzej Sapkowski "The Witcher. The Last Wish" (Повiсть)

The white-haired witch Geralt of Rivia, one of the few representatives of the once numerous trade of defenders of the human race against the creatures of inhuman evil, travels through small kingdoms that can be seen from the castle tower and large cities, receiving payment for what he has been trained to do - destroying eyelashes and munchkins, strigas and whippersnappers. But the witch also has his own code, in which murder is only a last resort, and a reasonable life, whatever it is, is still a life. This is how he makes new enemies, but also finds friends who will change his fate someday.
