Celebrate Christmas with us with Bewitching Hour by Anne Stuart, the kind of book where you know going in that there's gonna be a blizzard and the roads aren't the only things getting plowed.  Sibyl is evidently a witch who's a secretary for other witches and Nick is a skeptic about everything except dowsing.  There's also a haunted house that nobody ever mentions again and a late-game crime caper.  I don't even know, y'all.
