All the Pleasures of the Season — Lecia Cornwall

On the first day of Christmas:

Lady Miranda Archer accepts a marriage proposal.

On the first day of Christmas, fifteen minutes later:

Miranda realizes she's made a huge mistake.

For the next twelve days:

Miranda must find a way out of her engagement -- which is harder than it looks, especially since her fiancé is pompous, mean, and desperate for her family's jewels -- and convince her true love that all she wants for Christmas is him.
