The Tower of the Swallows is a 4th book in a fantasy saga The Witcher written by Polish author Andrzej Sapkowski. Compared to the previous books in a saga to me it has more plot, is the bloodiest one, has a lot more characters which are thrown in the plot and doesn’t have long-lasting effect. And for my taste it’s too much non-linear because I struggled a lot connecting the dots which part of the story is happening in the future or in the past. It’s obvious author experimented with different writing techniques but I especially liked (found amusing) the one where he finished lot of chapters with the same story arch with almost identical paragraph .
Other thing I enjoyed are philosophical debates between book characters and there are quite few of them: for example how law punishing criminals in cruel way creates the world it’s indented to prevent, how to fight evil (i.e. not by turning the other cheek, but teeth for a tooth, both eyes for an eye),
This book showed me for real that the main character of a saga isn’t Gerald but Cirilla (Ciri), his one-time ward and a child with extraordinary powers. So maybe title The Witcher also refers to Ciri? I write this because I was introduced to this amazing set of books by a video game Wither 3: The Wild Hunt where Gerald is the main playable character and thus you’d presume it that way. Great game, but books are even better.
