Harry Potter Series

I finished Harry Potter and the Half-Blood Prince and am working on Harry Potter and the Deathly Hallows. The thing that is incredible to me is that book #7 ties in ideas from the beginning books; the first snitch Harry caught, the Deluminator, and the sword of Godric Gryffindor. Within each book an elaborate story is woven, yet that is only on a micro level compared to the whole. On a macro level, all seven books act as chapters in an elaborate story about an unlikely hero. Bravo, J.K. Rowling.
