In 1946, war-weary Rose Grantham leaves the grim, ravaged streets of London on a whim, hoping to rediscover who she is and where she came from. Mousehole is a pretty little village in Cornwall with a turbulent past and undercurrent of betrayal, grief and destruction beyond the sparkling blue of the sea and the whitewashed cottages. For Rose, it offers the promise of anonymity, rest and renewal. Or, so she thought. As she investigates deeper into the mysteries of the past, and experiences her first taste of love, she finds that her quiet journey of self-discovery may be much more than she had once anticipated.
