Guarding Her Dragon by Julia Mills

What happens when a Christmas elf with way too much sass for her little pointed ears finds a centuries old Guardsman buried in the snow?
Well, she takes him home and nurses him back to health, of course.

If only everything was that easy. With six older sisters, two baby reindeer and an evil gnome of an auntie hellbent on world domination, Elsa’s got her hands full.
It’s gonna take more than a little lven magic and the love of her dragon to make it to Christmas Eve, but this little elf is not giving up. She’s guarding her dragon with all she’s got and finding out the best things in life might just come wrapped in glittering green scales.
