Following a troubled childhood, Sybilla Nygard marries her much older entrepreneur partner, Tobias Ocampo. They've been inseparable since they started Offbeat Enterprises together. Their publishing house produces a book series focused on unusual homes.

After suffering memory loss about his past, Tobias inherits an elaborate, isolated estate at the top of Bloodmoon Mountain in Bloodmoon Cove. The reports and rumors swirling about the house, suggesting death and secrets hide within, make it all the more appealing to Syl as their next Offbeat Homes project. But her biggest motivation is discovering more about Tobias's beginnings. Although Syl and Tobias don't relish spending winter trapped in isolation, they bring along their closest family and friends to keep them company while they search out the mysteries of Howling Halls.

The nightmare Syl has been having as long as she can remember returns. The voice of a ghost urges, Find me, leading her to hidden spaces and the skeletons of a family desperate to escape its demons...all while monstrous things are waking up hungry.
