THIS BOOK IS AMAZING AND IT IS MY FAVORITE BOOK! I read this when I was in fifth grade and I LOVED it. There were just so many cliffhangers and I just could never wait to read the next chapter. My class and I read this as a read aloud in fifth grade and it was my favorite book so for Christmas that year I got the book and I read it at least 50 times.i recommend this book to anyone in 4th grade and above.
