It is a compelling tale of love, belonging, and revenge.
Murakami's style allows you to nearly hear the music played in the background in the taxi which carries us to a parallel universe.
All the substories are very interesting, but they do not give much away about the general direction of the book. There are a lot of red herrings, but in the end you feel that the book is heading where it should.
Sorry for the cryptic language, but I do want want to put spoilers in.
There are obviously many layers and dimensions, and we see events from different points of view.
There is a strong feminist aspect to the book, and religous beliefs are discussed.
My favourite aspect is that you have the impression you could actually cook the recipes in the book.
It will not disappoint.
