Oh, please don't get me wrong. This book is adorable. I mean, come on - it's about a kid who wants to go save his mom. It's also a great stonking adventure with lots of flashy prose and a sweep-me-up-and-never-drop-me plot. Fun, fun, fun. 
 The only real problem I have with this book is the same that I have with pretty much every other fantasy tale that follows suit with Greek mythology: Medusa. 
 Just don't get me started. I don't really want to get into a rant about it, so let's just say that in ancient Greece they were perfectly happy to go right ahead and blame the victim. Consider this the next time you read anything about how eeeeeeevil Medusa is.
