Andrzej Sapkowski's The Witcher - The Last Wish
A collection of six stories with events that precede the main Witcher novels. In them, Geralt of Rivia is resting in a temple, recovering from battle wounds. He has flashbacks involving a bar fight, bodies in a forest, a party for a princess, and more.
Recommended as an introduction to Sapkowski's excellent Witcher series!
