It's a while since I read any China Mieville. My favourite was 'The Scar'. I loved the language of the prologue, and read that part over and over. Great maritime setting. I remember enjoying 'The City and The City'. I have 'Railsea' which I did not like so much. It is well written but I found the idea of a whole landscape covered by railtracks to be a bit far-fetched, and the ending did not work so well for me. I have probably read one or two more of his from the public library but I do not remember now.
