As an archeologist for the Bureau of Indian Affairs, Syd Walker spends her days in Rhode Island trying to protect the land's indigenous past, even as she's escaping her own. She's haunted by a night of violence she barely escaped in her Oklahoma hometown fifteen years ago. Though she swore she'd never go back, when a skull is found near the crime scene of her youth, just as her sister, Emma Lou, vanishes, Syd knows she must return home. The deeper Syd digs, the more she uncovers about a string of missing indigenous women cases going back decades. To save her sister, she must expose a darkness in the town that no one wants to face - not even Syd.
