Query: ...about crazy birds

I think the book is well written. There are a lot of tension and the tension is kept throughout the whole book. The situation of Nat and his family is shown well because you just see Nat's point of view and so you know how he sees that crazy situation of having millions of birds attack his family. You can feel the danger of the bird attacks and the fear and the helpness of the whole population.I think the story isn't very difficult to understand. It's written in an easy English. Alfred Hitchcock took the idea of the birds' attacks from Du Maurier and made a great film out of it. But the story is very different from the book - only the bird's attack ia still the same.
