The Forgotten Ghosts of Deadwood. Horror, #9

Sixteen-year-old Mina Ortiz expects fake scares when she spends the summer in Deadwood's ghost museum-but the town's real ghosts have been erased from history. When a siren sounds at 2:17 a.m., forgotten children rise, demanding to be remembered before they take what they're owed. As Mina uncovers a buried ledger of stolen names, she must lead a dangerous roll call that could free the dead-or bind her to them forever.
The Forgotten Ghosts of Deadwood is a chilling YA horror about memory, guilt, and the terrifying cost of forgetting.
