Hannah Hickok and Cooper Wyatt are newly engaged and ready to celebrate. Cooper just didn't think the celebration would involve a hike to a long-abandoned boom town called Blackridge. He had something more romantic in mind. Despite that, he agrees ... and believes the trip will be fine, right up until they stumble across a homeless man warning them away from their destination.
Hannah tries talking to him but the man is out of it, to the point where she recognizes he needs medical help. They manage to call the local sheriff to provide that help, but when the team he brings to carry the individual out of the valley crosses the Blackridge border, a wave of magic ricochets back and knocks Hannah for a loop.
She recovers quickly, but there's a question as to what happened. Once back in Casper Creek, that question becomes a concern. It seems the ghostly shadow that appeared in Blackridge at the time it fell more than a hundred years before is back, and now he's focused on Hannah.
The dark man is more than a ghost. He's more than a shadow. He's a monster who can straddle two worlds. He needs Hannah to lift the curse that has kept him trapped for a century, and he's more than willing to threaten those she loves to make it happen.
A new sort of terror has come to town, and Hannah has no idea how to fight him. She's a strong witch, but she's also a new witch, and when this battle lands on her doorstep, it's going to be a doozy.
Buckle up, because it's going to be a bumpy ride.
