Journalist Grace loves her son Jack with all her heart but she can't quite understand why, since his birth, she has felt at odds with herself. And – to add to her worries – she is still as heavy as she was at nine months pregnant and can't remember the last time she put on make up without leaving streaks across her face or smudging her mascara. This is a far cry from the glamorous Health and Beauty Editor she used to be but when the office bimbo reveals that all her colleagues have been talking about her about her back, things come to a head. The magazine Grace works for wants her to be a guinea pig, someone who will be the subject of their little experiment to have someone's life transformed. Yes, this may involve taking some happy pills. It may involve crying like an eejit in front of her hard-nosed editor Sinead, being weighed in public, and wondering whether or not she wants to stay married…but happiness always has some sort of price. Doesn’t it?
