It's Twelfth Night!

From The Twelfth Night Wager:
It was a dull day at White’s the day he agreed to the wager: seduce, bed and walk away from the lovely Lady Leisterfield, all by Twelfth Night. But this holiday season, Christopher St. Ives, Viscount Eustace, planned to give himself a gift.

While doing my research for the story, I enjoyed vicariously living through the Autumn season in Regency England and Christmastide which ends in Twelfth Night, January 5th. Twelfth Night has its origins in ancient Rome and was a mid-winter event observing pagan fertility rites, a festival of feasting and public celebration. At some point, this tradition became incorporated into the Christian celebrations and included feasting, drinking, games, plays, dances and masked balls. See MORE.
