This novel is rather displayed as a collection of stories (which will often be the case in the series), no obvious link between them, but still presents Geralt, in many facets. If the impression was that none of these stories has any connection with the others, we will discover in the following books in truth, many things are linked.
Only negative point of this book: the rough translation and uninspired (fortunately it gets better in the following books!)
In short, do not be fooled by the pretty average translation, and take time to appreciate the history.
