Christmas-themed romance novels

Christmas books -- whatever happened to them? I used to love to read the regency novellas and other holiday themed books, but I saw relatively few of them this year. Those that I saw were either contemporaries or authors that I don't recognize. In fact, at least one that I saw was a compilation of previously published novellas. The only holiday book that tempted me wasn't new, nor was it even romance -- it was Christopher Moore's The Stupidest Angel: A Heartwarming Tale of Christmas Terror. And since it was in hardback (currently subject to a moratorium, due to budget constraints), it stayed on the shelf.

The only holiday themed books I read this year were Carla Kelly's Marian's Christmas Wish and MaryJanice Davidson's Undead & Unreturnable. U&U is really only nominally a Christmas book: although set in December, most of the book focuses on vampire goings on, and vampires don't celebrate Christmas. Marian's Christmas Wish is an excellent, excellent Christmas book; Carla Kelly does excellent holidays. Truly, her novellas were the best parts of the old regency holiday anthologies that I've read.
