A remote island in the Scottish Hebrides, 1446. Teenaged midwife Rosie MacBain is skilled at what she does; whether that be delivering a baby, setting a bone, or keeping her four orphaned sisters from the brink of destitution. But on the day her youngest sister discovers an ancient piece of silver buried on their land, an old face from Rosie's childhood returns to the village. From that moment on, Rosie must decide which is more important to her. Her craft, her sisters, her lover...or her life.
