When Alice Ahmadi discovers a famed emerald necklace while interning at a struggling Parisian magazine, she is plunged into a glittering world of diamonds and emeralds, courtesans and spies, and the long-buried secrets surrounding the necklace and its glamorous former owners.

When she realizes the mysterious Honeybee Emeralds could be her chance to save the magazine, she recruits her friends Lily and Daphne to form the “Fellowship of the Necklace.” Together, they set out to uncover the romantic history of the gems. Through diaries, letters, and investigations through the winding streets and iconic historic landmarks of Paris, the trio begins to unravel more than just the secrets of the necklace’s obsolete past.

Along the way, Lily and Daphne’s relationships are challenged, tempered, and changed. Lily faces her long-standing attraction to a friend, who has achieved the writing success that eluded her. Daphne confronts her failing relationship with her husband, while also facing simmering problems in her friendship with Lily. And, at last, Alice finds her place in the world - although one mystery still remains: how did the Honeybee Emeralds go from the neck of American singer Josephine Baker during the Roaring Twenties to the basement of a Parisian magazine?
