Illiterate

I just finished a "chick lit" book my sister-in-law lent to me (along with several others I've devoured in the four days since), and I was left with the question, "How exactly does this qualify as 'lit'?" I know chick lit isn't supposed ot be Anna Karenina, but even though I enjoyed the book, it was really just a thinly disguised romance novel, but not nearly as satisfying. I guess I'm just not a "chick."
