Friday the Witchteenth

Bay Winchester is newly married and happy. Things have been quiet since she returned from her honeymoon, which means trouble is just around the corner. When it comes, it takes the form of a despondent man on a bridge. Despite her best efforts, Bay and the hostage negotiator can't save him, and death is swift.
That should've been the end of it, but a weird symbol on the dead man's hand piques Bay's interest, and when the negotiator turns up sick with the same symptoms, she knows that they have a problem on their hands.
Suicide as a contagion? It's not the fight Bay was expecting, and it's definitely not the one she was looking for. Still, it's the problem that keeps on giving ... especially when it spreads to Mrs. Little.
In her heart, Bay knows that she shouldn't care about the woman who has hurt her family at every turn. Ignoring the problem isn't an option though. If she stands back and does nothing in an attempt to end the chain, she'll never be able to live with herself. If she gets too close, she could get infected herself.
Bay has never doubted her magic, but the current fight is out of her wheelhouse. Magic is at the core of what's happening, but their enemy is invisible.
The Winchester witches have never met an enemy they can't fight ... until now. Will they be able to pull together and save Hemlock Cove? Or is the town doomed to fall to a curse without a name and an evil without a soul?
Strap in, because the answer is more than anybody is expecting, and if everybody is to survive, the fight will have to move to an entirely new level.
The game is on. In this one, the winner will take all.
