WOW, great book! I could barely put it down. It is shelved in GR in Children's section, although it is not. It has conspiracies, murders, torture... And that twist!
I loved Sage's character, so rebellious and grumpy and clever.
Right now I can't write a proper review without giving too many spoilers, but it was really good. Started a bit slow but I grew fond of all characters eventually.
