Oh Georgia, how you make me laugh.
I've been reading the Georgia Nicholson series by Louise Rennison for a while now. It's very cute and fluffy and just fun to read. Georgia is a self-centered teen who's life is dominated by her friends and boys. If I am ever feeling down and need a laugh, I can depend on Georgia to make me full of laughosity. I laugh like a laughing thing in laughland when reading one of her books.
I totally recommend this series to anyone with a sense of humor. They are great to read in between serious and/or long books. The books are very quick reads and will brighten any one's day.
