Since childhood they have been inseparable friends

Lorn, Lewis, Ruth and Rachel. The close-knit community of Rhanna has watched them grow up - playing and fighting together, seeing each other through the bad times. But now they are grown and they face a harsher world, and all the problems of love and loss for which their tranquil Hebridean upbringing cannot prepare them. Yet all four know that whatever might happen, however far they drift apart, they are still and always children of Rhanna.
