Midwinter in Meryton (A Festive Pride and Prejudice Variation #3)

Snow has separated one dear couple, but might it be the very thing to reunite another?
Elizabeth Bennet's Christmas is a quiet one, with heavy snowfall preventing anybody coming and going from Longbourn. She is puzzling over how to reunite her sister with Mr Bingley when Mr Darcy crosses her path, and offers to do the thing she cannot: to summon Mr Bingley back to Netherfield, and to Jane.
Fitzwilliam Darcy returned to Hertfordshire on a fleeting errand, never thinking he would find himself snowed in alone for Christmas. Surprised not to enjoy his involuntary isolation, he makes his way on foot to Longbourn, and finds in the Bennets the warmth and society he didn't know he needed.
Can a bitter Meryton winter warm his heart and lead to love?
