Anthony Trollope 
Mistletoe Bough 

Another of Trollope’s stories about love, marriage, and the difficulty of uniting in matrimony. Elizabeth Garrow used to be engaged to marry Rodney Holmes, but it was broken off for some mysterious reason which the former refuses to divulge. All it takes is for Elizabeth’s friends and a bough of mistletoe at Christmas to get the ball rolling. (Goodreads)
