Mature

Here's all the stories that feature more mature heroes and heroines. While "mature' is a very broad category, in this situation, it includes anyone older than than their late thirties.

Honor & Redemption
A Passing Fancy
Beneath the Mistletoe
A Light in the Dark
Once Upon a Winter's Eve

Spinsters

Contrary to popular belief, ladies in the 1800s weren't considered spinsters until they were about thirty (in fact the average age for women to marry at that time was closer to twenty-four to twenty-five). So, these are books that feature true spinsters, though there are others that feature heroines who are inching toward that designation.
