Some towns have ghost stories. Ravenwood has evidence.
After moving to Ravenwood, twelve-year-old Lily Sinclair discovers an abandoned mansion where reality twists, strange creatures hide in the woods, and whispers follow her wherever she goes.
Refusing to believe it's all in her imagination, Lily forms the Paranormal Detective Agency with three other outsiders. Their investigations uncover forgotten secrets, impossible phenomena, and a growing threat that could tear open the boundary between worlds.
To save Ravenwood, they'll have to solve the town's oldest mystery before the darkness finds them first.
