A simple spell had gone disastrously haywire and now there was a woman running around London who looked exactly like her--a woman with no sense of propriety whatsoever.

To find her double and set things right, they'd have to work together--braving the fog-shrouded streets, a mysterious group called the Brotherhood, and a passion stronger than any magic. less
