With Halloween around the corner, Shay Myers is brewing witchy seasonal sips at Crystals and CuriosiTEAS--while simultaneously steaming over pub owner Liam Madigan's decision to take anybody but her to the town's Monster Mash dance. Her romantic premonitions have missed the mark since she settled into coastal Bray Harbor, opening the door to questions about whether she's really the gifted seer her late mother imagined. It's why she second guesses the dark vision in her tea leaves about a local citizen and their obsession with genealogy, Irish folklore, and magic . . .

But when bad omens come true, Shay doesn't have time for self-doubt. A woman's body has been discovered, frozen in a strange pose with an eerie black butterfly on her forehead, leading to suspicions that the victim took a conjuring ritual too far due to limited experience--or was murdered by someone with too much. As an investigation stirs up a sinister connection to a boardwalk mystic shop, Shay, guided by her knowing dog, Spirit, finds herself tracking down a shady figure from her past, navigating the sudden reappearance of her ex-husband, and chasing down a wickedly perceptive criminal who might finally be her match!
