Lots of fun, more fairy-tale like than many Regencies.

Isabella Chilcott sneaked into the masquerade ball, wearing a dress she found in the attic. She had a marvelous time despite identified as an imposter shortly afer arrival. What to do, what to do, should she stay with Mr. Boring or seek true love with the Duke?
