Lizzy and Darcy have been happily married for a year, and family and friends are gathering at Pemberley for the Twelve Days of Christmas, including the notorious brother and sister from Austen's Mansfield Park, Henry and Mary Crawford. Every day of the twelve brings new surprises, some shocking, some wonderful. Romantic liaisons and family drama make for a roller coaster of a holiday season in this Regency Jane Austen variation.
