The BEST Science Fiction Book YOU HAVEN'T READ

I finished this book in less than 48 hours because I could not put it down I absolutely needed to know what happened next and I thought Greg Egan masterfully set up a number of mysteries solved those Mysteries and then quickly established a new one.

There are so many awesome ideas in that book which I think could have been their own novels and yet sishinlu just kept on cranking out the ideas just like Greg Egan does in permutation City.
