Kerri Bloodstone inherited a vineyard, an old house, and a family secret that hums beneath her skin. When her Bloodstone pendant suddenly answers an ancient call, the quiet town of Anoka ripples with impossible events: a kidnapped housekeeper, newborn twins who teleport, and shadowed cultists hunting artifacts that bend time. With her friend and lover Allen by her side-and a scraped, loyal cast of town guardians-Kerri is forced to learn the language of her blood and the tech of a vanished civilization.

As the autumn equinox approaches, the Witching Tree's roots remember what they were built to guard. The Nemracki want the gateway it hides; Kerri wants to keep her family safe. To succeed, she must master a legacy of lightning and lineage-but owning that power might cost her the life she hoped to protect. Who will survive when the thresholds open, and what must be sacrificed to lock them again?
