Double Enchantment (Relics of Merlin #2)

Lady Jasmina was in a world of trouble. 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. All Society was whispering, and a baronet she'd never met was suddenly acting like he knew her...in a most intimate way. 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. Rated '3/5 - Open door' for steam/spice/heat level.
