Kissed by the Knight by Cecelia Mecca

Two unlikely childhood friends—the baron’s son and baker’s daughter—are finally reunited.
Sir Tristan rides into the gates of Camburg Castle just in time for the holiday festivities, his seven months in France having been the longest of Reina’s life. She has missed her friend dearly and is ready to celebrate his safe return.
Until she learns of Tristan’s impending betrothal to another.
Suddenly, the magical season loses its appeal. The only man she’s ever loved, admittedly one she could never claim as anything but a friend, might soon be lost to her forever.
Thirty years after the Border Series ends, a new saga of family, loyalty, and love along the turbulent Anglo-Scottish border begins.

Authors Note: If you like short prequel stories, multi-generational families, friends-to-lovers romance and holiday magic with a bit of extra spice, put Kissed by the Knight on the top of your reading list.
