Meet Me Under the Mistletoe by Jenny Bayliss
This was very sad for being a Christmas book. This book focuses on Nory and her school friends who are all getting together for a wedding. But one of them isn't there because he killed himself a few years ago. And at his funeral Nory slept with Guy and it wasn't until afterwards that she found out Guy was married so obviously she feels horrible. Fast forward to the wedding week and she now meets the wife how is wonderful and she wants to tell her but doesn't because it's his problem and his marriage so he needs to do it (and his marriage is in enough trouble because he's the worst). They are staying at the castle adjacent to where they all went to school and it's good and bad. The son of the former gardener is now the head gardener and he's hot and Nory is interested in him and they hit it off despite the Marquis no fraternization policy and her older brother trying to keep them apart. Then he shows her his family's big secret; his great great grandmother was a painter and a really rich family took credit for her work. So she tries to help him buy getting Guy involved because he's a great investigative journalist but Guy tries to make a move on her and even though she tries to fight him off Isaac walks in and sees and he ends things with her. They break up and both are miserable. She returns home for Christmas and her brother needs her help to deliver some centerpieces up at the castle which helps them get back together. Fast forward one year and they get married. The friends from the previous year have a baby and name it after their dead friend and everyone is happy. But the undercurrent of their dead friend was prevalent throughout the entire story and it was too real and too sad for a happy holiday story. When you are expecting a cute Hallmark story it's surprising to get a real story with fully developed characters who can have sad backstories and baggage. I think I prefer my holiday books to be more fluff and less real.
