Description: The last installment of The Keys to the Kingdom, a series of seven young adult fantasy novels by Garth Nix, the main character's mother is stuck within a time-loop. Lord Sunday is the first son of The Old One and The Architect. He wields the seventh Key, and rules The Incomparable Gardens. He has ultimate authority in the House, but tends to leave the charge of the day-to-day affairs to his next-in-command, Superior Saturday, who has sought to prevent the implementation of the Architect's Will. One of the Seven Trustees, Lord Sunday defied the Seventh Part of the Will of his mother and, along with six other Trustees, keeping his demesne and Key for himself rather than yielding it to a human heir, believing that the transition of the Architect's powers and authority to a mortal to be inappropriate. He reveals that he only defied the Architect so that he could keep on tending to his Garden. Each of the Trustees is afflicted with a deadly sin. Six of the seven have been portrayed, leaving only pride for Lord Sunday.
