Jane and Marnie have been inseparable since they were eleven years old. They have a lot in common. In their early twenties they fell in love with and married handsome young men. But Jane never liked Marnie's husband. He was always so loud and obnoxious, so much larger than life. Which is rather ironic now, of course.

Because if Jane had been honest - if she hadn't told those lies - then perhaps her best friend's husband might still be alive . . .

This is Jane's opportunity to tell the truth and, as she narrates their shared history and unpicks each of her seven lies, she reveals the pockets of darkness that have infiltrated their friendship and the toxic secrets still bubbling beneath. It's a novel about obsession, grief, the dark corners of even the closest friendships and what it means to tell your version of the truth.
