Mistletoe is a Vampiric Plant: Hallowedspell Vimp novella 2

Naughty or Nice...Going to Grandma’s for Christmas never got so complicated. The McAllister family had yet to tell Gran Wilson that they had learned the adopted daughter they had raised from a baby was a Vimp—a demon that was a cross between an imp and a vampire. They had learned it just last Halloween. But since they hadn't told her on Thanksgiving--it was Christmas or never.

Can a demon celebrate a Christian holiday?
