Interior designer, Bailey Davis was minding her own business, and that of her clients when on a job site just outside of Chicago, when she runs into her ex. Annoyed and harassed, she nearly falls into a pit intended for the new swimming pool, but instead loses a precious memento. When she goes back to retrieve it, Bailey finds more than a diamond bracelet. She finds old human bones that someone will kill to keep hidden. Threatened, attacked, and kidnapped, Bailey eventually meets gorgeous Detective Declan O'Connor, of the Chicago Special Investigative Division, who has a few secrets of his own. Together they dive into the perilous underworld of the Guild, where unbeknownst to humanity, creatures of the night roam the world. Their journey takes them from the glittery big city of Chicago to the sultry lowcountry of South Carolina on a desperate search for the truth about her sudden and unexplained powers, who her true family is, and a monster who has Bailey under his control.
