Plot Summary

Halla of Rutger’s Howe, a 36-year-old widow, inherits the entire estate of her great-uncle, Silas, but her late husband’s relatives, Aunt Malva and her son, Alver, are determined to keep the wealth in their family. When Halla refuses Alver’s marriage proposal, they lock her in her bedroom. After three days of captivity, with her relatives insisting that she will remain imprisoned until she agrees to the marriage, Halla decides to kill herself, reasoning that her death will guarantee that her own nieces inherit the estate.

Searching for a means, Halla takes an old, sheathed sword from the wall. As she prepares to fall on the blade, she draws it, triggering a flash of blue light. A man materializes, introducing himself as Sarkis, the servant of the sword. He explains that he is magically bound to serve and protect whoever wields the sword. After Halla explains her desperate situation, Sarkis declares they must escape together.

Halla packs her few belongings, and Sarkis kicks down the locked bedroom door. They confront Alver, Malva, and the family guardsman, Roderick. Sarkis engages Roderick in a duel, sustaining a wound to his arm and severely injuring Roderick’s sword arm. Halla and Sarkis flee the house, evading the town constables, and eventually make their way out of the town.

On the road, Halla and Sarkis hide in ditches and find shelter in an abandoned hut. Halla tends to Sarkis’s wound, and he explains that he heals from any injury, even death, when he is inside the sword. Halla says they should go to the town of Amalcross to seek help from Silas’s friend, Bartholomew, then to the capital, Archon’s Glory, to petition the Temple of the White Rat for legal aid. During their journey, Halla learns that Sarkis is from a northern land called the Weeping Lands and has been bound to the sword for centuries. At an inn, a woman named Mina lures Halla into an ambush, but Sarkis appears and easily disarms the bandits. He and Halla continue their journey and are later stopped by priests of the militant Hanged Mother order, whom Halla deflects with a rambling story.

They travel to Amalcross and meet Bartholomew. Because he is an avid collector of unusual objects, they keep Sarkis’s true nature a secret during their stay at Bartholomew’s house. They continue to Archon’s Glory, where they meet a priest and lawyer of the White Rat named Zale. After they consult with the bishop, the Temple agrees to represent her. At the city library, a historian helps them determine that Sarkis has been bound for 450 years. Moved by this discovery, Sarkis kisses Halla. Later, they are ambushed by robbers who attempt to steal the sword, but Sarkis fights them off.

Zale accompanies them back to Rutger’s Howe in a temple wagon, which is driven by a badger-like “gnole” named Brindle. Along the way, Zale and Halla conduct experiments to understand Sarkis’s magical nature, and they are harassed multiple times by priests of the Hanged Mother. When one priest shoves Halla, Sarkis attacks and kills the priest, and Brindle kills his companion with a crossbow. They are forced to hide the bodies in a frozen pond.

The road then magically transports them into the uncanny Vagrant Hills. There, where they encounter the rune, a race of stag-men who offer to free Sarkis from the sword. He declines, unwilling to abandon Halla. That night, a flying, gelatinous creature attacks them. After evading a whole host of similar creatures the next day, they escape the Hills and return to the normal world. They stop off at Bartholomew’s house again, meeting his guest, a scholar-priest named Nolan. Bartholomew, who witnessed Silas’s will, agrees to travel to Rutger’s Howe independently to testify on Halla’s behalf.

Nearing Rutger’s Howe, Halla, Sarkis, Zale, and Brindle are ambushed by highwaymen. Sarkis is shot with an arrow, and Halla sheathes the sword to save him. The bandits, who were tipped off by Mina, capture Halla, Zale, and Brindle. Eventually, the healed Sarkis materializes and quickly kills several bandits, driving off the rest. They return to Rutger’s Howe, where Zale confronts Malva and Alver. A formal judgment is held, and with Bartholomew’s testimony, the will is upheld, making Halla the legal heir.

That night, Halla and Sarkis become lovers. The next morning, overcome with guilt, Sarkis has Nolan read the sword’s inscription, which reveals that he was put in the sword as a punishment for betraying his employer. Feeling betrayed to realize that Sarkis is not a true hero, Halla renounces her ownership of the sword, sheathing it and leaving in a huff.

Sarkis is soon summoned by Bartholomew, who has claimed ownership of the sword and is conspiring with Nolan to acquire it for Nolan’s order. Sarkis attacks, but the sword’s magic prevents him from harming his new wielder. Meanwhile, Halla returns to the house to find that Sarkis is gone and that Zale has been captured by Alver and Malva. Zale and Halla escape their confinement and confront their captors. In the struggle, Halla stabs Alver in the arm, and they flee to call the constables, leading to Alver’s arrest.

Rescued from another confrontation with the Hanged Motherhood by paladins of the Dreaming God, Halla, Zale, and Brindle travel back to Amalcross with a swift escort. They find Bartholomew murdered by Nolan, who is now Sarkis’s wielder. Halla offers her inheritance for the sword, but Nolan refuses. She threatens him with a crossbow, and Nolan commands Sarkis to defend him. Magically compelled to fight Halla, Sarkis instead kills himself, returning to the blade. Halla shoots Nolan in the leg and forces him to renounce ownership of the sword, making her the wielder again. Nolan is arrested for murder.

Halla waits a fortnight for Sarkis to heal. When she draws the sword, he appears, and they reconcile and confess their love. Sarkis proposes, but his people’s tradition requires that the husband pay a “marriage price” for the bride, which he cannot afford. Zale negotiates a symbolic price on Halla’s behalf, and they are wed.

Months later, Halla and Sarkis are living happily in Rutger’s Howe. They receive a letter from Zale, who warns that Nolan, before dying in prison, revealed that his order would soon acquire the “second sword,” hinting at the existence of another of the Smith’s creations.
