For me when I was 13 Harry Potter was getting more popular I was reading books what my nan was reading, the likes of Let's Meet on Platform 8 by Carole Mathews and House of Echoes by Barbra Erskine, which was mainly based for adults, so when I got the change to read Harry Potter I read the first 30 pages and I just couldn't get into it at all. However when Twilight came out I think I gone back a stage and got back into the Chick romance books, however it wasn't just the geek girl fall in love with popular boy, boy don't notices girl, girl end up with him at the end, it was something different, the boy wasn't just a boy, there was something else about that boy, he was a vampire and it was like he could kill her anytime, I wanna see what happens with him. However there are better vampire books out there then Twilight. If I do end up reading Harry Potter again, I might just end up liking it.
But as for the Films, I do prefer Harry Potter.
