The Goblins of Christmas — A.C. Ellas

It's Christmas time in Athens, and when George discovers that his Rovani partner, Yeraki, has never celebrated the holiday, he and the rest of their taverna band gleefully fill Yeri in on the mythology surrounding the Christmas goblins who wreak havoc in any house that isn't blessed.

Yeri announces that he's going to catch these goblins, and the hilarity ensues as the goblins unleash twelve nights of pranks and practical jokes on them. Life may never be the same for the pair, assuming their sanity survives what's coming.
