Rosemary’s young, just at college, and she’s decided not to tell anyone a thing about her family. So we’re not going to tell you too much either: you’ll have to find out for yourselves, round about page 77, what it is that makes her unhappy family unlike any other. <br><br>Rosemary is now an only child, but she used to have a sister the same age as her, and an older brother. Both are now gone – vanished from her life. There’s something unique about Rosemary’s sister, Fern. And it was this decision, made by her parents, to give Rosemary a sister like no other, that began all of Rosemary’s trouble. So now she’s telling her story: full of hilarious asides and brilliantly spiky lines, it’s a looping narrative that begins towards the end, and then goes back to the beginning.
