That reminds me, I'd love to get a semi-resonable set of all the HP books (price-wise). Preferably hardcover. I've been meaning to read them for YEARS but never have and I've only seen a few of the films, which I've really enjoyed.
I hope you like them. They are all page turners and they really pick up starting at the 3rd book. From then on there's some excellent history and detail in their little world.
The series as a whole probably doesn't get enough respect for how imaginative it is despite it's popularity because every time you hear of it it's "zomg harry potter! gryffindor!"
Out of all the long series of books I've read so far (Dark Tower, LOTR..and some others i can't remember right now) it's probably the one that ended the best.
