I really loved this book it was the best Middle-Grade book that I have read in a long while. I really loved the characters even more than before especially Alastor and Prosper I liked the other characters as well. I really liked how Prosper's and Alastor's relationship developed into a really good friendship it grew so much that they would do the unthinkable to save the other. I really liked the plot of the story it started out as Prosper and company going to save his sister and it just grew from there I really loved how the story ended it had the perfect ending. So overall I really loved this book and would read more like it by this author.
