There are some really great things about this book. While I am not a big fantasy reader, and I (gasp!) don't know who this David Eddings person is everyone keeps referring to when talking about this novel, I will say that it held my attention when most fantasy books do not do so - so props first for that!
It's very much about the world building and fantastical characters and situations, but it's primarily about the love story between two women, a thief and a knight. I enjoyed the characters, and wish there were more of them - but the supporting characters are definitely important and pertinent to the story.
I did have a little trouble following the structure and the timelines, but the prose was fantastic and beautiful and elegant and I really did enjoy it.
