An excellent read. I could not have read a better book than this one in quite a while. If you like reading stuff that is out of ordinary and breaks literati-set-rules then go for this novel.
My observation was that the author was clearly into his first project (and bang on). There were problems in between (plot becomes slow), but the surprises were very neatly set in to wash all that off.
I would give this book a 8 out of 10 on all aspects and would recommend it to be read by 16+ only.
