Good Witch: Season 3

Middleton gets transformed into a town where "it's always the day before Halloween" when the author of a series of magic-and-romance-filled novels comes to Grey House to celebrate the release of her newest book, titled "The Enchantress Unites." But it's Cassie who ends up doing the uniting, bringing together the people of Middleton to put on the special event (and helping the author find love of her own) while also coming to a special realization about Sam.
