A review of The Fantastic Secret of Owen Jester from a 7-year-old reader on Amazon:
This is a really good adventure book, and is also a friendship book. I'd say that if "Charlie and the Chocolate Factory was a "10" then this book is a "12". I'm planning to read it again. I think my dad should read it too.
I liked this book a lot, it was really detailed. Even though there weren't any pictures in the book, the author described things so well that I could imagine everything very clearly. The only girls in the story were Owen's enemies, but I think girls would still like the rest of the book.
