Tess Venture inherits her grandmother's inn, prompting her to leave the island for the first time and find her place in the world. With the promise of uncovering answers of her witchy origins and meeting sisters she never knew existed, she arrives in the sleepy unfamiliar town and soon discovers that her grandmother's inn is even stranger than the island Tess left behind. Tess stays in the monstrous house the town people believe should be demolished, taking care of people she doesn't know for a woman she's never met. She's required to make good on guest obligations she didn't even make before any answers about her family are revealed. When the first death omen appears before she's even unpacked her suitcase, all clues point to mysteries surrounding her grandmother's death, where, just like everything in this town, nothing and no one seems as they appear and a killer is walking free.
