Tall, thin and blonde

Best friends Jenny and Amy have no time for Miss Perfect Teenagers, the tall, thin blondes whose only talk is of boys and fashion. At least they didn't. Now suddenly Amy's changed: she's into salads and diet Cokes; she's got a new hairstyle, wardrobe and set of friends. Jenny, meanwhile, finds herself part of a group of oddballs nicknamed the Martians. Will she follow Amy or find her own way?
