Tristan Fitz-James, the Marquess of Bridebourne, has been in love with his best friend, Lady Sophia Rowan, his entire life. He's about to propose at Christmas when fate cruelly pulls the lovers apart. Two years later, when they meet again at the same holiday house party, they're enemies. Tristan has earned a reputation as a London libertine, and Sophia wants nothing to do with him. He broke her heart once, and she vows it’ll not happen again. When they're locked together in a room during a festive game of hide and seek, secrets and passions flare in the dark until they're discovered by other guests. There is only one solution that’s honorable. Marriage. Tristan is determined to win back Sophia even though she would rather throw away her reputation than marry the man who stole her heart then stomped on it. Undeterred, he vows to find a way to show her how good they are together. It’ll take more than mistletoe and holiday goodwill to mend these broken hearts and bring the two of them together again. Yet, Tristan has always believed in Christmas miracles. He just has to show Sophia that Christmas present and the promise of Christmas future will overcome their past. Under the Marquess' Mistletoe first appeared in Kindle Vella.
