The series follows the story of seven sisters, and begins as their adoptive father – the elusive billionaire they call Pa Salt – dies, and they are each given a tantalising clue to their true heritage. Each book is the story of one of the sisters as they trace their origins all over the world in spellbinding tales of love and loss.
The first book in the series is The Seven Sisters; followed by The Storm Sister, The Shadow Sister, The Pearl Sister, The Moon Sister, The Sun Sister and The Missing Sister. The eagerly awaited final book of the series, Atlas: The Story of Pa Salt came out in May 2023.
