Lady Friday
Arthur Penhaligon's adventures in the House get ever more perilous as the week unfolds. On the fifth day, there was fear...
Four of the seven Trustees have been defeated and their Keys taken, but for Arthur, the week is still getting worse. Suzy Blue and Fred Initial Numbers Gold have been captured by the Piper, and his New Nithling army still controls most of the Great Maze. Superior Saturday is causing trouble wherever she can, including turning off all the elevators in the House and blocking the Front Door.
Arthur can't even find out what is happening back home. All he knows is that Leaf isn't on earth any more. She's missing and so are hundreds of other people who were transferred from regular hospitals to a private institution run by a "Doctor Friday". From there they have been taken somewhere else in the Secondary Realms, for Lady Friday's own horrible purposes.
Amid all this trouble, Arthur's mother is also missing, and he must weigh up an offer from Lady Friday that is either a cunning trap for the Rightful Heir or a golden opportunity he must seize – before Superior Saturday or the Piper beats him to it.

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.
