Mild spoilers. Murakami is hit or miss for me. I had trouble finishing the book, I felt the character development was handled very poorly. If a story has no development it can be frustrating, but his handling of Aomame was just strange. The strong person in the first two books just sort of vanishes and it becomes all about Tengo. I wouldn't put it past myself to have missed something, though.
Interesting, I'll have to relay what I thought once I finish it!
I came into this one after reading Norwegian Wood, which I loved so I didn't/don't really know what to expect.
