This week's theme comes from Alexandra. In honor of Pottermore early registration (whether we registered early or not or even care about such things), this is the week to talk about a favorite book series in more detail than was previously done. We've given an overview - now let's get into minutiae. Dig down deep and go in depth on your favorite character, favorite plot point, favorite pet theory -- whatever you like! Sky's the limit, and there's no such thing as too much Potter!
