I couldn't vote a ten, but I assure you, it was a ten for me.
I cried when Ptolemy died. Same with Nathaniel.
Ok I just spoilt this for people who didn't read it yet.
Nathaniel turns back into Nathaniel in the end. I hated him in the first parts.
I hope Stroud makes an extension of the Trilogy, about Ptolemy or something, since Nathaniel has died.
