Title: interesting and mysterious
Review: I think it's mysterious because they never tell you the secret of V.F.D. I kept reading the book because I thought it might tell me the secret. I was sort of disappointed that they never told me. I recommend this book because it's very interesting and slightly confusing and it has plenty of surprises.
