This is an article written by Shannon Hale (most of you know how much I love her) and it pretty much sums up my feelings exactly.
It's not that I don't like the classics (I do, promise) but this explains why I love books like Shannon's or the Twilight Series. I love the stories and characters. I can devour Twilight a million times (and I am getting close to that :) because of the story in the book. That's the whole reason I fell in love with reading in the first place. (And yeah, I read Nancy Drew under the covers, too)
