December 1st. Angie and her teenage son Rust prepare for Christmas, stringing
fairy lights around their isolated home on the Somerset levels and decorating a tree
with traditional ornaments. The first door of the advent calendar is opened, but the chocolate inside tastes off. Rust receives his first Christmas card; it's unsigned, and the message is 'pinch, punch... first of the month'. The robin chirruping on a bough in a snowy woodland picture looks like a nasty piece of work.

The cards keep coming, one each day and each more sinister than the last, and a
frightened Angie recalls 'The Cards' - a seasonal TV show from her childhood that featured similar happenings, and while she remembers it vividly, there is no evidence that it was ever broadcast...

Christmas cheer is gradually poisoned, with cruels instead of carols, the turkey rotting in the fridge, unwelcome visits from the Merciless Gentlemen and the Jingle Basterds, and Rust becoming increasingly unwell. Angie begins to wonder if her childhood Christmases were in fact as joy filled as she remembers...

A frightening tale of seasonal dread from the acclaimed author of Anno Dracula. Cosy traditions are made twisted and terrifying as a mother and son grapple with their painful past.
