An Oprah's Book Club selection, this gripping and powerfully wrought novel from the bestselling author of The Weight of Water is a stunning meditation on grief, betrayal and 'the ultimate unknowability of those closest to us' (Daily Telegraph) Who can guess what a woman will do when the unthinkable becomes her reality? Being married to a pilot has taught Kathryn Lyons to be ready for emergencies, but nothing has prepared her for the late-night knock on her door and the news of her husband's fatal crash. As Kathryn struggles through her grief, she is forced to confront disturbing rumours about the man she loved and the life that she took for granted. Torn between her impulse to protect her husband's memory and her desire to know the truth, Kathryn sets off to find out if she ever really knew the man who was her husband.

In her determination to test the truth of her marriage, she faces shocking revelations about the secrets a man can keep and the actions a woman is willing to take. 'Enthralling' -Anita Brookner, author of the Booker Prize-winning Hotel du Lac 'Compellingly told, brilliantly observed, lyrically written and when you get to the last page you simply want to run out and buy everything she's ever written' -Sunday Independent
