I like this book I already read "Spy School" by the same author. I preferred Spy School but in this story it explains and you find out more about this character and SPYDER. Would not recommend to read this before reading spy school you will not understand much but I would recommend this series.
I gave this book 2 stars because i found it weird and confusing. I read this book in school I didn't understand half of it. I watched the movie same thing. I don't like this book but if you are a fantasy ,fiction ,or Mythology fan you would like this book.
