I'm Cat – and I'm the fat, plain one in my family. When I say fat, I don't mean 'have-to-be-prisedout-of-a-hoola-hoop' fat, but when your mum and sister are practically size zero, it's hard not to feel like the elephant girl in comparison.
My twin sister Tessa is blonde, gorgeous and gets any boy she wants. Right now she's got her eye on Josh, a really fit American guy who's just moved to Glasgow.
But he doesn't seem that interested in her.
It's weird. I've never known any boy who didn't fancy Tessa.Well, not straight ones, anyway . . .
Of course! It all makes sense . . . funny that he doesn't want to tell anyone about his secret, not even me, his new best friend . . .
Could Cat be jumping to conclusions about Josh, in this wonderfully funny tale of romantic confusion?
