As Mac delves deeper into the mystery of her sister’s death, her every move is shadowed by the dark, mysterious Jericho…while at the same time, the ruthless V’lane – an alpha Fae who makes sex an addiction for human women – closes in on her. As the boundary between worlds begins to crumble, Mac’s true mission becomes clear: to find the elusive Sinsar Dubh before someone else claims the all-powerful Dark Book – because whoever gets to it first holds nothing less than complete control both worlds in their hands.
