The six D’Aplièse sisters have each been on their own incredible journey to discover their heritage, but they still have one question left unanswered: who and where is the seventh sister?

They only have one clue – an image of a star-shaped emerald ring. The search to find the missing sister will take them across the globe – from New Zealand to Canada, England, France and Ireland – uniting them all in their mission to complete their family at last.

In doing so, they will slowly unearth a story of love, strength and sacrifice that began almost one hundred years ago, as other brave young women risk everything to change the world around them.
