Two lonely, lived-in, thirty-somethings. One boring wedding. One heated encounter in a quiet cloakroom.

It's not exactly the recipe for love. And John and Jane's time in a cloakroom clearly isn't the beginning of anything real; even they know that. When they manage to pull back, literally, it occurs to them that they might start this whole thing over, properly. They might try getting to know one another first. But they live on opposite sides of the country. So they agree to write.

And they do. What follows is a series of traded and shared confessions: of their messy sexual and emotional histories, their first shy, callow relationships, their past errors and their big loves, their flaws and their passions. Each story of a love affair - confessed with striking honesty - reveals the ways in which both Jane and John have grown and grown up, changed and not changed, over the years; the people they hurt, the ones still bruised, the ones that bruised them. Where all of this confession will take them is the burning question behind every letter - one that can only be answered when they meet again, finally, in the flesh...

This is a remarkable novel - indeed a tour-de-force - in its extraordinary well-observed insights into the way we live now, of mating and dating in a post-feminist time, of the negotiations between the sexes in the challenging world of equal but different. Written by a man and a woman, it is not only remarkable, it is unique.
