If Every Day Was Christmas, by Donna Ashcroft
This is as much family/small town drama as it is romance. The heroine owns a Christmas shop and is obsessed with all things festive as it’s the one time of year her parents manage to get on, and she’s determined to have the perfect day by herself with no drama. The hero is a rockstar who’s come to hide out in her tiny village and pretend to be a normal boring bloke. He hates Christmas because of his ex-wife. Of course the heroine’s family show up and start causing problems. Also, there are reindeer. It’s not the most plausible story, so if you don’t get on with books where you have to suspend your disbelief, maybe give it a miss, but it’s a lovely bit of escapism.
