Arthur Penhaligon is not supposed to be a hero. He is, in fact, supposed to die an early death. But then he is saved by a key shaped like the minute hand of a clock.
Arthur is safe – but his world is not. Along with the key comes a plague brought by bizarre creatures from another realm. A stranger named Mister Monday, his avenging messengers with blood-stained wings, and an army of dog-faced Fetchers will stop at nothing to get the key back – even if it means destroying Arthur and everything around him.
Desperate, Arthur ventures into a mysterious house – a house that only he can see. It is in this house that Arthur must unravel the secrets of the key – and discover his true fate.
