Superior Saturday
On the Sixth Day, there was Sorcery
Arthur Penhaligon has wrested five of the Keys from their immortal guardians, the Trustees of the Will. But gaining the Sixth Key poses a greater challenge than any he has ever faced before. Superior Saturday is not just one of the Trustees, she is also the oldest Denizen and the most powerful and knowledgeable sorcerer within the House. She has tens of thousands of sorcerers at her command – and she has been preparing her forces all along for the Will's escape and the activities of the Rightful Heir. Everything is all just part of a greater plan she has been hatching for ten thousand years.
As Saturday's schemes become evident, Arthur is beset on all sides. Nothing is eroding the House, and only the power of the Keys can hold back the tide of destruction. His mother is still missing. His home city is under attack. His allies are unreliable. He can't even get into the apparently impregnable Upper House and even if he does, finding the Sixth Part of the Will and gaining the Sixth Key might not be enough to counter Saturday’s sorcerous hordes or stop her bid for ultimate power.

Garth Nix
In Garth Nix’s worlds, the dead rarely stay quiet, magic obeys ancient and perilous rules, and courage often looks like a teenager holding a bell, a sword, and the weight of two realms. Best known for the Old Kingdom series, Nix has carved out a space in fantasy literature that hums with mythic resonance and emotional depth—where necromancers clash with free magic creatures and heroines face destiny with grit rather than grandeur.
Born in Melbourne, Australia, Nix grew up in Canberra, absorbing stories that blurred the line between the ordinary and the extraordinary. He worked in bookstores, publishing, and even the Australian Army Reserve before turning his attention fully to fiction. That eclectic journey quietly shaped his writing—there’s a sense in his stories that the fantastical doesn’t sit apart from reality, but seeps into it through forgotten doorways and ancient bloodlines.
The Keys to the Kingdom
The Keys to the Kingdom consists of seven books. The current recommended reading order for the series is provided below.
