Snow is falling, hot cocoa is calling. She wants his first Christmas to be perfect, but something is screwing with their holiday. Calan has been a Chevalier his entire life and has never celebrated a single holiday. What’s this about a fat man invading your home with magic to leave gifts? Calan’s powers have always been used for fighting demons and dark spirits from the Stygian, but now he must learn that the Christmas Spirit is not the kind you exorcise. Emma wants Calan to know the joys of a real Christmas. Snowed-in together, in a modern mansion devoid of Christmas warmth, none of their family or friends are able to join—it’s up to Emma to make sure Calan completes the Christmas checklist of perfect holiday activities. But something’s in the house and it’s naughty…not nice.
