I liked the characters in the book, and how even though they are completely different from each other, as in they are different species and have completely different attitudes, they are able to work together to save each other. I really liked how the author had Amelia use physics throughout the book and I liked the friendship between the five chaoses and how they children never stopped trying to save each other. I liked that the author used the Greek gods as characters in the book, because its interesting to read of these gods and goddesses, that once were considered everything and now are considered a myth, be put in a world where the majority of people don't belive they ever existed. The author also did a good job in putting the story of Aphrodite's and Ares' relationship in the story. I liked this book better than the first book, though. The first book ended on a kind of sad note because the kids were getting their memory erased and their only hope at remebering was really small, but the at the end of this book they've escaped from the school and they're boat to freedom is coming and just ends on such a more optimistic note than the first book. All in all it was a very good book and I can't wait to read the next in the series.
