Kennedy Bennett comes from a long line of curse weavers. For centuries, her family has plied their trade in Unstable, Massachusetts, an unconventional small town that's welcomed paranormal practitioners since the dawn of spiritualism. Kennedy has recently struck out on her own, opening an antiques shop in Boston, where her specialty is uncursing and reselling hexed objects. Then Aiden Connolly walks into her life with an offer she really should refuse. The scion of a wealthy family of luck workers, Aiden has a scheme to get his hands on the most famous cursed object of all.

Detective Casey Duncan has noticed fewer and fewer residents coming in to the hidden town of Rockton, and no extensions being granted. Her boyfriend, Sheriff Eric Dalton, presumes it’s the natural flux of things, but Casey’s not so sure. It seems like something bigger is happening in the small town they call home.

Thorne Manor has always been haunted...and it has always haunted Bronwyn Dale. As a young girl, Bronwyn could pass through a time slip in her great-aunt's house, where she visited William Thorne, a boy her own age, born two centuries earlier. After a family tragedy, the house was shuttered and Bronwyn was convinced that William existed only in her imagination. Now, 20 years later Bronwyn inherits Thorne Manor. And when she returns, William is waiting. 

Every season in Rockton seems to bring a new challenge. At least that's what Detective Casey Duncan has felt since she decided to call this place home. Between all the secretive residents, the sometimes-hostile settlers outside, and the surrounding wilderness, there's always something to worry about. While on a much needed camping vacation with her boyfriend, Sheriff Eric Dalton, Casey hears a baby crying in the woods. The sound leads them to a tragic scene: a woman buried under the snow, murdered, a baby still alive in her arms.

The secret town of Rockton has seen some tough times lately; understandable considering its mix of criminals and victims fleeing society for refuge within its Yukon borders. Casey Duncan, the town's only detective on a police force of three, has already faced murder, arson, and falling in love in the several months she's lived there. When a US marshal shows up demanding the release of one of the residents - but won't say who - Casey and her boyfriend, Sheriff Eric Dalton, are skeptical. Then, hours later, the marshal is shot dead.
