Airhead - my desert island book

If there was one book i would bring on a desert island it would be Airhead by Meg Cabot. I bought this with a book voucher i got and i bought the whole series at the time which three books. I loved these books they were so good. I got them when i was twelve. The books are about this girl and she never really cared about her looks, her younger sister was always wearing makeup. she brought her younger sister to a model show because her younger sister really wanted to go. The older sister and the model had to switch brains because a TV fell on the model and she had to get a brain transplant. The older sister has to live a life of a model it is really intresting I love it!!!
