Three enigmatic sisters. A Boxing Day hunt gone awry. One story, the real story, is finally coming to light.

1999: When successful writer Gillian Larking receives a letter from the nephew of an old friend, she knows that her past has finally caught up with her. Violet Claybourne, her old boarding school roommate, was a girl who captivated Gillian with stories of her charming sisters and their picturesque home at Thornleigh Hall.

Violet Claybourne pulled Gillian into her life, into her family, and changed Gilly's path forever. Violet Claybourne also spent the past sixty years in a psych hospital, and now she wants Gillian to tell her story.

The real story.

1939: Gillian knew upon meeting the Claybourne girls at Thornleigh Hall that they were something more. Rich, enigmatic, bright, unafraid of the world around them, a foreign concept to quiet, unassuming Gilly. Meeting Violet, Emmeline, and Laura was like entering a new world. Gilly longed to be a part of them, and when a terrible Boxing Day hunt goes awry, she gets that wish. But only in a way more terrible than she could ever have imagined. Soon enough Gillian has to confront just how deep her loyalty to the Claybourne girls runs, and what it might cost her, and them, in the process.
