Which book do you find yourself regularly rereading, and why?
I guess it'd have to be Harry Potter.
I remember the first time my sister told me about the 1st Harry Potter book. She was going on about this boy locked up in this cuboard, how his parents had died, and all this abuse he was suffering. Me and my siblings just laughed in her face, and said no one would write about such terrible things. We were quite young (we'd never read something so serious), so even when she followed through with it and said that she wasn't lying, we just told her we didn't believe her at all and she just left it at that.
Couple of years down the line, I was looking through the school library. Spotted the philoser's stone and devoured my way through the pages. It turned out to have the same plot, and me not connecting the dots, rushed up to my sister to tell her about the similarities. So then she laughed in my face, and told me it was the same story. She also mentioned it was a book for losers and how she'd been right all along.
I thought whatever and just kept reading it, and I fell in love with the series. Even now, "ages past", my sister rubs it in my face, how if it wasn't for her, I never would've found them. But considering how there are movies out and all that merchandise bullcrap, It'd be surprising if I never noticed the books anyway. So the reason why I keep reading them is because it's an awesome chain of a story with a lot of depth. I guess I've grown up with them, and people in the future will probably read the stories too, but I can say to my grandkids that I was around when the last Harry potter book had just come out, and how it was the end of such a great bunch of novels. Woah, that was long!
