Each of the books in this series is very different from each other, and this last was no exception.As Sophos' story, it was very different. I feel like this is really the only thing that the book could have been about, but I didn't quite like it as much as the others, for some reason. I'm not quite sure why, because I did like Sophos, and I was engrossed in his story, and delighted by the interactions between him and Eddis. However, when everything was revealed in the end, I felt a bit confused, like I might benefit from a re-reading.
