Won't give a rating, as I gave up on it about 4 chapters in.
I know a lot of people love it - but I was bored out of my mind and had to relisten over and over to take anything in, as nothing was actually happening - no plot, just lots and lots of talking. And while good dialogue will keep me entertained - this felt like it was trying to be philosophical, but didn't manage to catch me that way either.
I returned it.
