Bay Winchester thinks the only thing on her to-do list is a memory spell to make Aunt Tillie’s archnemesis forget all the bad things that have happened to her in recent months. When the spell almost backfires thanks to an error on Aunt Tillie’s part, things almost spiral out of control and she’s annoyed. That annoyance turns to fear when on their way home they find a vehicle in the middle of the road. It’s running, but nobody is in it. A quick search leads Bay and Evan to three bodies in the woods. And they didn’t die of natural causes. When the FBI arrives on the scene, Bay has a choice to make. She agreed to help with their new paranormal unit, and it seems they’ve finally found a case. Just what will this new partnership entail, though? Bay wants to help. Even more, she wants to be part of a team. What if the team she already assembled was better than her new one, though? There’s a monster on the loose, and it is not done killing. If anything, it is just getting started. On top of that, Bay has family problems coming out of every cauldron. Aunt Tillie is up to something, Thistle is covering for something, and Landon just found out he no longer has an eight-pack. Bay has a lot on her plate. There’s no turning back, though, because if she doesn’t find the monster, it will find her family. And it won’t stop until everybody is dead. Bay is the mightiest witch in Hemlock Cove. Even she might not be able to fight this darkness.
