Demons of Christmas Past — Colleen Vanderlinden

Marriage between two demonic beings is bound to be a challenge, but Molly Brooks never expected to feel like she and her husband, Nain, would start drifting apart the way they have. Between her endless responsibilities in the Netherwoods and his role in Detroit's supernatural community, they go days at a time with barely a chance to speak to each other.
Add to that life with two challenging toddlers, family lurking around at every moment, and a castle full of imp guards, demons, and immortals, and it's no wonder the magic seems a little… less magical.

Their family and friends have been urging them to take a rest, but both stubbornly resist, bound to duty in ways neither of them expected. When Nain gets injured, they're forced to face the fact that maybe it's time for a break.

And Molly knows exactly where to take her 300 year old husband… well, not where, exactly. But when.

On a trip that enables them to not only reconnect with the city they love, but with each other as well, they discover that they have unresolved issues between them, and that there is so much more to making a relationship work than just wishing it.

In this Hidden twist on a beloved O. Henry story, Molly and Nain will face off against gangsters, demons, and sometimes their own family, but in the end, they'll discover just how much stronger they truly are when they're together.
