The Seven Sisters. The Lost Sister

Thanks to the will of their adoptive father Pa Salt, each of the six D'Aplièse sisters was able to embark on a unique journey to the lands of their ancestors and uncover the mystery of their birth.
But one question remains unanswered. Who is their lost seventh sister, who Pa Salt never adopted? Where should they look for her?
The D'Aplièse sisters have only one clue – a ring with seven emeralds.
From New Zealand to Canada, France, and Ireland – the brave women of the D'Aplièse family set off on their journey once again.
Before them unfolds an amazing story of love and self-sacrifice, the beginning of which was laid almost a century ago.
Welcome to the colorful under-starlit world of the D'Aplièse sisters.
