The Summons
Sabriel, a young woman at a boarding school in Ancelstierre, a land with weak magic, is nearly finished with her studies. She has a unique tie to the Old Kingdom, a magical land separated by a wall, because her father is the Abhorsen, a necromancer who lays the dead to rest. One day, a terrifying, partially reanimated messenger from the Old Kingdom crosses the wall. It brings a small satchel containing her father's Abhorsen bells and sword, along with a note saying he is in danger and she must take his place. This event changes her ordinary life, pushing her into responsibilities she knew would come, but never expected so soon.
Crossing the Wall
Following her father's instructions, Sabriel uses her inherited powers and the Abhorsen's tools to cross the Great Wall, leaving Ancelstierre's safety. The Old Kingdom is full of Free Magic and restless Dead, and she immediately encounters hostile spirits and dangerous creatures. She quickly learns to use her necromantic abilities, ringing the bells to control the Dead and using the sword for protection. During her journey, she finds a human-like creature trapped in a magical sleep. She frees him; he is a powerful, though amnesiac, companion who calls himself Mogget, often changing into a white cat.
The Road to the Abhorsen's House
Sabriel and Mogget continue their journey toward the Abhorsen's House, a place of power and safety. Along the way, they face many threats from both the living and the dead, including tricky Free Magic constructs and strong spirits. Sabriel improves her skills with the Abhorsen's bells and sword, learning the details of her necromantic duties. Mogget, despite his memory loss, offers advice and shows strong magical abilities, often saving Sabriel from danger. Their path is difficult, forcing Sabriel to face her destiny and the Old Kingdom's dangers.
The Abhorsen's House
At the Abhorsen's House, Sabriel finds it mostly empty but full of her father's lingering presence and past struggles. She discovers a hidden library with old texts and records, which tell her more about the Abhorsen's family line and the Old Kingdom's magic. Through these findings, Sabriel learns that a powerful Free Magic being, Kerrigor, is waking up and is likely why her father disappeared. She also finds hints about Mogget's true identity and his long history with the Abhorsen line, suggesting he is more than a simple magical being or pet.
The Red Lake and the Clayr
To understand Kerrigor's full threat and her father's location, Sabriel decides to seek the wisdom of the Clayr, an old group of seers in a mountain fortress. The journey to the Clayr's Glacier is dangerous, involving crossing the Red Lake, which has powerful spirits and magic traps. Sabriel and Mogget navigate these dangers, strengthening their bond. At the Clayr's Glacier, Sabriel learns more about Kerrigor's history as a powerful Dead creature who wants to break the Charter and unleash chaos on both the Old Kingdom and Ancelstierre. The Clayr's visions confirm her father is imprisoned and she is the only one who can stop Kerrigor.
Meeting Touchstone
Following a vision from the Clayr, Sabriel and Mogget travel to the Great Rift, a desolate and dangerous area. There, they find a mysterious figure in a crystal prison, a victim of a powerful Charter Magic spell. This figure is Touchstone, a long-lost Charter Mage and former prince of the Old Kingdom, imprisoned for two centuries. Sabriel, using her growing Charter Magic abilities, frees him. Initially disoriented and weak, Touchstone gradually regains his strength and memories. He reveals his royal connection and his knowledge of Kerrigor's past, making him an important ally in Sabriel's quest to find her father and defeat the threat.
The Search for the Abhorsen
With Touchstone now part of their group, Sabriel, Mogget, and Touchstone continue their search for the Abhorsen. Their journey takes them through increasingly dangerous areas, where Kerrigor's influence is clear in the many powerful Dead creatures and the weakening Charter Magic. They follow clues and use their combined knowledge to find her father's likely location, a place deep within the Old Kingdom where the barrier between life and death is thin. Sabriel faces more challenging necromantic tasks, learning to control stronger spirits, while Touchstone offers historical context and tactical advice, drawing on his past as a prince and mage.
Into Death
Their quest leads them to a gateway into Death itself, the realm where the Abhorsen traditionally lays the dead to rest. Kerrigor, a powerful Free Magic being who has escaped Death, has imprisoned Sabriel's father within this realm, using him to further his dark plans. Sabriel, with her Abhorsen bells and sword, bravely enters Death, a series of nine dangerous gates, each guarded by stronger, older spirits. Mogget and Touchstone go with her, supporting and protecting her as they navigate the afterlife's treacherous landscape, facing powerful Dead creatures and the very fabric of existence. Failure would mean Kerrigor's release and the Old Kingdom's collapse.
Confrontation and Sacrifice
Within the final parts of Death, Sabriel confronts Kerrigor directly. He reveals his plan to fully re-enter the living world and destroy the Charter, plunging both the Old Kingdom and Ancelstierre into endless chaos. Sabriel's father, weak but alive, is held captive by Kerrigor, who uses him as a tool. A fierce magic battle begins, with Sabriel using all her necromantic skills and the bells' power against Kerrigor's ancient Free Magic. During the fight, Sabriel faces a terrible choice: sacrifice her father to fully banish Kerrigor back into Death, or risk Kerrigor's ultimate victory. She makes the painful decision, using the final bell to bind Kerrigor, even though it means her father's permanent passing into true death.
The New Abhorsen
With Kerrigor banished and her father laid to rest, Sabriel emerges from Death, changed but determined. She has fully accepted her destiny as the Abhorsen, understanding the immense responsibility and lonely duty it brings. Touchstone, having regained his full strength and memories, pledges his loyalty and support to the new Abhorsen. Mogget, his ancient and powerful nature hinted at, remains by her side. Sabriel begins the difficult task of healing the Old Kingdom, laying to rest the many Dead unleashed by Kerrigor and restoring the Charter Magic's balance. She and Touchstone start to rebuild, facing the Old Kingdom's future together, solidifying their roles as protectors of life and death.
