Christmas is a time for families to come together. Guin Roberts can’t think of anything worse than visiting a Christmas market with her new family. Guin is perfectly happy with her own company and doesn’t want that disrupted by her wisecracking stepbrother and his earnest mum. Their Christmas celebrations are invaded by a sleigh full of murderous elves. And it doesn’t matter if they’ve been naughty or nice—these elves are out for blood. Can the family band together to survive the night? Or will Santa’s little helpers make mincemeat of them all?
