Charlie's a sparky twelve-year-old who thinks she's too fat to get a boyfriend.

A mild flirtation with the boy in the local video shop is as far as she's got in terms of a romance.

She's enjoying e-mailing her German penfriend, Frank, but when he suggests coming over to visit, she panics.

She's sent him a photo of her skinny best friend, rather than of her, and now he'll find out...There's no way he could be interested in her for herself - is there?
