From the New York Times bestselling author of Eon and Eona; a Regency adventure series starring a stylish and intrepid Buffy-esque demon-hunter**

London, April 1812. On the eve of eighteen-year-old Lady Helen Wrexhall's presentation to the queen, one of her family's housemaids disappears-and Helen is drawn into the shadows of Regency London. There, she meets Lord Carlston, one of the few who can stop the perpetrators: a cabal of demons infiltrating every level of society. Dare she ask for his help, when his reputation is almost as black as his lingering eyes? And will her intelligence and headstrong curiosity wind up leading them into a death trap?
