Massive / Julia Bell.

"Weight has always been a big issue in Carmen's life. Not surprising when her mum is obsessed with the idea that thin equals beautiful, thin equals successful, thin equals the way to get what you want. And soon this obsession starts to take over. When her mother sweeps her off to live in Birmingham - taking her away from her stepfather, the only good influence in her life - Carmen finds things spiralling out of control. And she begins to ask: if she was thin, could it all be very different?" -- Provided by publisher.
