Yes! It’s called Blessed Winter. It’s a no-room-at-the-inn romance starring Brock,the brother of the groom in Cruel Summer, and Pandora, a pregnant waitress alone on Christmas Eve.
The catch is, Blessed Winter is written by Glory, my heroine from On The Edge. So you can only read Blessed Winter by reading On The Edge.
It’s more of an Easter egg than a Christmas book, now I come to think of it. Let’s call it a stocking stuffer, maybe?
I set it up like a real book, though, and made a cover for it, since it has a plot and everything. Read more about it here, but if you follow the buy links, they’ll take you to On The Edge.
