New York, 1925. Cranky and jaded Lord Fine—Wesley, now, to the kindhearted lover he cynically doubts life will let him keep—arrives in Manhattan with one goal: find the American paranormals and get their help with the relic burdening Sebastian. His plans are upended when the other paranormals seem to have vanished, and a mysterious letter warns Wesley that he’s in danger. Sebastian has no doubts when it comes to his feelings for Wesley, but he’s still haunted by the time he spent enthralled by blood magic right here in New York. And now, his magic is unstable, bolstered by a relic that seems to drain energy from his very blood. Chasing a trail that leads from Fifth Avenue’s bootleggers to a Halloween masquerade at a Tarrytown mansion, they must race to find their friends before devastation is unleashed on New York—and on magic everywhere.
