Althea Demea has a simple life running the bookstore she owns with her mom, Blade & Ink. Her days are “boring,” but thankfully, she has her best friend, Mallory, who believes that Thea needs to experience more in life, thus creating the “dating bets.” They have all been failures until she meets Lukas.
With preparations for the Halloween party, Thea is eager to dance the night away with Lukas. During the party, Thea discovers she’s a Guardian Witch—the Triple Goddess’ disciples who possess witchcraft—attracting the Slayers, a ruthless group that hunts her kind. The Halloween party turns into chaos, putting everyone’s lives in danger.
Saving Mallory’s life, Thea summons the King of the Underworld, who is none too pleased that a soul has been taken from his realm. Thea exchanges her soul for Mallory’s, and as the terms of their agreement change, Thea embarks on a quest to recover the lost map to the Great Library, which the Slayers are also seeking.
