The big day is finally here. Bay and Landon's wedding day has arrived. Unfortunately, a tragedy stands in the way of their happily ever after, and it comes in the form of reports of an armed gunman at the local high school. Bay, ghosts at her side, braves the scene to save the kids ... and uncovers something horrific. She. The boy with the gun says he needs to find her. The teacher in the room with him says the same thing before taking his own life. There's a magical being in Hemlock Cove, and she's wielding a great deal of power as she forces people to kill in her name. Bay refuses to back down, convinced that the magical explosion they can't get under control at Hollow Creek is partially to blame. The problem is so big, another witch needs to be tapped to help them solve it. Scout Randall, part of the Spells Angels group in Hawthorne Hollow, is more than happy to lend her services. She owes the Winchesters a favor after all. She simply might not be enough. Bay and Landon have been through more than any couple should have to survive ... and they're not done. Here comes the wedding ... and Clove's baby ... and the worst enemy they've ever fought. The Winchesters are strongest together, and this time they're going to prove that there's no keeping a good witch down. I do? It's coming, because nothing can stop these witches when love and family are on the line.
