From the author of One Puzzling Afternoon and perfect for fans of Sarah Penner and The Foundling comes a slow-burn gothic mystery following a young girl enthralled by a set of enigmatic sisters, their house at Thornleigh Hall, and the tragedy that binds them together for good.

1938. She is lonely and away at boarding school, used to going unnoticed. But then she meets her vibrant roommate who takes her under her wing. Her roommate is unlike anyone she has ever met, and she regales her with tales of her grand family estate and her two elegant sisters. She is soon entranced by stories of her sisters, so when she is invited to meet the family at Thornleigh Hall, she can't believe her luck.

But she soon finds that behind the grand façade of Thornleigh Hall, darkness lurks.

Dazzled by the crumbling manor and her roommate's enigmatic sisters, she settles into the estate. But when a horrible accident strikes on the grounds, she is ensnared in a web of the sisters' making, forced to make a choice that will change the course of her life forever. Because the girls know how to keep secrets, even at the cost of one of their own.

This ensnaring prose contains layers of friendship, privilege, mental health, and characters you won't soon forget.
