Abhorsen Series in Order by Garth Nix

"Terciel and Elinor" is a novel by Garth Nix that tells the never-before-told love story of Sabriel's parents, Terciel and Elinor, set some years before the birth of Sabriel. The book is part of "The Old Kingdom" series, a fantasy series written by Garth Nix that includes six books. The story follows Terciel, a young Abhorsen-in-Waiting in the Old Kingdom, and Elinor, a 19-year-old girl who practices carnival skills across the wall in nonmagical Ancelstierre. After surviving an assault on her home through Terciel's timely intervention, Elinor takes a position at a magic-teaching girls' school, hoping to learn magic and prepare to travel to the Old Kingdom. When an incident sees her reunited with Terciel and whisked to the Abhorsen's House by a distant relative who reveals Elinor's connection to a sisterhood of seeresses, she finds that she is to play a vital part in the fight against a looming threat.

"Goldenhand" is the fifth book in "The Old Kingdom" epic fantasy series by Garth Nix. The book takes place six months after the events of "Abhorsen" and follows the novella "Nicholas Sayre and the Creature in the Case," which is featured in "Across the Wall". The story alternates between chapters about Lirael's flight back to her childhood home and her new romantic interest, a man who is an unsettling mixture. The book introduces new key characters, such as Ferrin, a young nomad woman who tries to cross into the Old Kingdom with a message for the Clayr about a terrible threat in the north. "Goldenhand" builds on the structure of the series to date and expands Nix's fictional world.

"Clariel: The Lost Abhorsen" is a prequel to "The Abhorsen Chronicles" and is part of the "Old Kingdom" series by Garth Nix. The book follows the story of Clariel, a young woman who lives in the town of Estwael and is destined to become a great hunter. However, her plans are disrupted when she is forced to move to the city of Belisaere, where she becomes embroiled in a political conspiracy and discovers dark magic. The book explores themes of power, destiny, and the consequences of one's actions. It is a standalone novel that can be read independently of the other books in the series, but it also provides additional context and backstory for the world and characters of the "Old Kingdom" series.
