This is a re-read for my RL book club as well.
This is the second time I have read Perdido Street Station. I enjoyed it far more this time. The first time I read it, I gave it three stars. Now, it's four.
It is a weird novel that would also work for the cryptozoologist square.
It traces the paths of scientist in a city. He is hired to make a winged being fly again, but he then gets caught up in rebellion. The world building is wonderful. It is like a cross between Dickens and Dr. Who. There is much in the book about government and rights, and class, and moths, and bugs, and icky stuff.
I do wish, however, that the central female lead didn't disappear for a large section of the book.
