Mortal Follies - Alexis Hall
It is the year 1814 and Miss Maelys Mitchelmore finds her entry into the highest society of Bath hindered by an irritating curse. It begins innocuously enough, with her dress slowly unmaking itself over the course of an evening at the ball of the season, a scandal she only narrowly manages to escape.
However, as the curse progresses to more fatal proportions, she realises she must seek out urgent assistance, even if that means mixing with the most undesirable company-and there are few less desirable allies than the brooding Lady Georgiana Landrake-who may or may not have murdered her own father and brothers to inherit their fortune.
If one is to believe the gossip, she might be some kind of malign enchantress. Then again, a malign enchantress might be exactly what Miss Mitchelmore needs.
