In this second volume of this series, there is a thrilling adventure they will be taking to find the book and find out what the person was going to do with it. There are twists and turns throughout it. The suspense and magic throughout the the novel kept my attention to find out what will happen next. The characters are portrayed realistically. I learned some interesting information about the Aztecs. At the end of the novel is a list of the Aztecs’ names and how to pronounce them. I thoroughly enjoyed reading this novel and can’t wait for the third one to be published! I am a definite fan of this wonderful series.
