Julie Anne Long's "Between the Devil and Ian Eversea" (#9 in the Pennyroyal Green series)

Between the Devil and Ian Eversea - Julie Anne Long

 

Aside from a couple of anachronisms (accordions had not been invented when the story takes place, sometime around 1815), and typos (the cook's name alternates pretty regularly between "Mrs. deWitt" and "Miss DeWitt"), this is a charming and highly enjoyable story.  

 

I'm *really* ready for Olivia Eversea's and Lyon Redmond's story, though.
