Query: I just couldn't put it down!

A beautifully written story on the life of Roald Dahl. Stupendous photographs and pictures. It seems as if you were right there with him. I thought the part on Llandaff Cathedral School was the best part. It makes me think he had a great life. Although it seemed like it should have a sequel, I'd still think this book was the best of the two. I think Roald Dahl's writings are amazing, but after I read this story, I thought his life was interesting too. I've been inspired by this book to write stories too. It amazes me that anyone could write stories this good.
