Emmy's dad disappeared years ago, and with her mother too busy to parent, she's shipped off to Wellsworth, a prestigious boarding school in England. But right before she leaves, a mysterious box arrives full of medallions and a note reading: These belonged to your father.
Just as she's settling into life at Wellsworth, Emmy begins to find the strange symbols from the medallions etched into the walls and stumbles upon the school's super-secret society, The Order of Black Hollow Lane.
Ancient buildings, strict rules, and a rigid uniform code shape her new reality. At night she wanders through the old library, hears whispers about former students, and discovers cold stone corridors filled with hidden mechanisms.
