One family brought together at their beautiful but remote childhood home when their father goes missing. The Whitethorn marriage – Graham and Patricia – has always been the subject of high praise. They’ve raised three children and live in a beautiful house overlooking the Cornish coast. But no family is as perfect as it seems… When Graham mysteriously vanishes, leaving a note to tell his wife not to worry, their children descend on the family home, bringing problems of their own. Amy has a new partner in tow (who she clearly can’t stand), and a secret to reveal… Stella is wondering if she ever knew her husband at all… Over one summer in Cornwall, the Whitethorns will lay bare all the secrets the lie between them…
