Query: My son loved it.

I bought all six of the Harry Potter books for my son. He grabbed Book 1 on Sunday and read it all the same day. He was captivated and said it is his favorite book he has ever read.I was afraid the book would be to difficult for him to read, he reads at a 3-4th grade comprehention level but apparently he did not have issues with the book.Highly recommended.
