We are all completely beside ourselves

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. 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: 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. Twice.
