Mister Monday, by Garth Nix

Arthur is not a hero – he’s just a boy with chronic asthma, a boy who is about to die. Until he is visted by two strangers from another realm who give him a strange key shaped like the minute hand of a clock.Although his life is saved, it is also changed for ever.

Arthur has been chosen as the heir to the keys of the kingdom. It’s not a role he particularly wants, but with a strange plague affecting his city and everything he knows at risk, Arthur must venture into the other realm and fight for his rights.

He must venture into a mysterious house that no one else can see and unravel the secrets of the key.

Mister Monday is the first in a new series, The Keys to the Kingdom by renowned fantasy author Garth Nix.Different from his previous series, the Old Kingdom trilogy, Mister Monday will nonetheless appeal to his fans as well as to those who have not read his previous works.
