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 what it is that makes her unhappy family unlike any other.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. So now she's telling her story; a looping narrative that begins towards the end, and then goes back to the beginning. Twice.It's funny, clever, intimate, honest, analytical and swirling with ideas that will come back to bite you. We hope you enjoy it, and if, when you're telling a friend about it, you do decide to spill the beans about Fern - it's pretty hard to resist - don't worry.
