A hidden ledger from the early 1800s resurfaces-bound in skin, inked in blood, and listing every Callahan born or yet to come. Each name is paired with a date. Some have already passed. Some have not yet.

As the pages begin to change on their own, the family uncovers a horrifying truth: the ledger does not predict death. It collects it.

Something ancient tied itself to the Callahan line long before they arrived in Wren Hollow, and now it has come to claim its debt. To stop it, they must face not just the haunting- but the origin of the curse itself.
