I loved the main story in The Witcher 3: Wild Hunt, so it was an absolute no brainer that I was also going to read all the books of this amazing dark fantasy series. The original story/books are written in Polish, so initially I was a little worry the English translation might be either not great or literally lost in translation, however The Last Wish: Introducing The Witcher was an enjoyable read. The Witcher universe has a lot of Eastern European folklore and mythology which I had to refer to Google to fully understand what Sapkowski was exactly referring too.
This is the first book of the massive and complex Witcher universe (The official Wiki has over 5k pages!). Amazing how reading the book, thanks to the video game I can picture the stories that it narrates.
NO SPOILERS: It was cool reading the backstories of Geralt himself, how he met Yennefer, his adventures with Dandelion, and most importantly to the Witcher saga itself, the relationship between Princess Pavetta and Duny. I also found it amusing that the books describes events that are exactly as of the major Walt Disney fairy tales stories, almost implying that The Witcher is the opposite of the traditional Disney fairy tales. As well as finally learning why Geralt dislikes traveling through portals.
