The Harry Potter series has got to be the best book series I ever read fantasy wise, and story telling wise. I've read all the books and even today I still get goosebumps when reading them, especially Order of the Phoenix, man that was a shocker. You'll be surprised with how quickly time flies when you are reading these books. The movies are also wonderful. My older sister loves the movies, I'm trying to get her to read the books now since she's a huge fan of the movies. My parent's still are shocked by the sheer size of the book volumes. I've been a Harry Potter fan for ages and I love the series.
RIP anime version of Glovehead. Pokemon Adventures will save you.
