And then, for the festively-minded there's What is Myrrh Anyway? which answers all the questions you've ever wanted to ask about the Christmas season, and some you haven't.
For the science fiction and fantasy fan in your family, why not try the Pax Britannia steampunk-action-adventure novels Unnatural History and Leviathan Rising?
And if you're looking for stocking fillers for the kids, you could do a lot worse than get them a few gamebooks - The Horror of Howling Hill, Howl of the Werewolf, Bloodbones, Curse of the Mummy, Spellbreaker - which will keep them occupied while you're getting Christmas dinner on the go. Or even Go, Go Crazy For Those Bones, for the younger GoGo's fan.
