It Happened Under the Mistletoe — Valerie Bowman

When Oliver Townsende escapes to his friend's house for a Christmas party, he intends to avoid the hordes of marriage-minded misses who have been dogging his steps in London ever since he inherited a dukedom. He soon learns a bit of Yuletide peace and quiet is too much to ask for. When he encounters Miss Cerian Blake, who's dodging her own unwanted set of admirers, the two decide to join forces and fake an infatuation to keep their suitors at bay. But when a bough of mistletoe becomes involved, will their Christmastime prank turn into a love to last all seasons?
