Full Summary

The novel opens with Lucie Herondale attempting a resurrection spell for Grace Blackthorn’s brother Jesse, but the ritual fails. Cordelia prepares for her wedding to James, a marriage of convenience meant to protect her family’s reputation after her father’s disgrace. At the Hell Ruelle, a faerie warns Cordelia that her husband does not love her. James’s bachelor party reveals his strange visions of Belial’s shadow realm, and his friends grow concerned.

During the wedding ceremony, James and Cordelia marry at the London Institute. The reception is tense: Elias Carstairs makes a drunken scene, and Thomas Lightwood threatens Alastair. Afterward, James and Cordelia move into a Mayfair home he has decorated with Persian art. They establish rules for their sham marriage and sleep in separate bedrooms.

Over the following weeks, Cordelia and James develop a comfortable routine, sharing games and intimate conversations. James gives Cordelia a gold globe pendant symbolizing their shared travel dreams. At a party, Grace Blackthorn’s arrival unsettles James. Meanwhile, Lucie discovers that Jesse can read her novel, which features a ghost lover; he is furious and disappears. Grace pressures Lucie to continue with dark magic.

A series of brutal murders begins. Basil Pounceby is stabbed to death, and James realizes he dreamed the murder in detail. More killings follow: Filomena di Angelo, Elias Carstairs (James’s father-in-law), and Lilian Highsmith. James fears he may be the killer, acting under Belial’s control while asleep. The victims are found missing permanent runes, spiritually stolen by a demonic stele called the pithos. James’s friends discover that the murder weapon is transferring runes to Jesse Blackthorn’s preserved body, making him an anchor for Belial’s plan.

Cordelia, feeling Cortana reject her after it burns her, seeks out Wayland the Smith. At the Uffington White Horse, Wayland heals the sword and binds Cordelia as his paladin. Later, Lucie and Grace bargain with Malcolm Fade for necromancy secrets. James ties himself to his bed to prevent sleepwalking, but still wakes with a sigil scratched in ice.

The investigation intensifies. Thomas Lightwood is arrested for murder but freed by the Mortal Sword. Alastair Carstairs admits he secretly followed Thomas and witnessed his innocence. Anna Lightwood and Ariadne Bridgestock grow closer. Lucie learns that Jesse’s body holds stolen runes and prepares to destroy it, but Grace knocks her unconscious.

James and Magnus Bane travel into the shadow realm on a chessboard, where Belial denies sending the murder visions. Cordelia pulls James back with Cortana. They kiss passionately, and James’s silver bracelet breaks. He collapses with black eyes, indicating possession.

Belial appears possessing Jesse’s corpse and reveals the murders completed a sigil that summoned the sea demon Leviathan to attack the Institute. Cordelia fights Belial with Cortana, but Lilith reveals she disguised herself as Wayland and made Cordelia her paladin. James shoots Lilith, scattering her. Lucie commands Jesse to expel Belial, which works. The group banishes Belial to outer darkness.

Afterward, James lies to the Enclave, blaming Jesse’s possessed body. Cordelia confesses she is Lilith’s paladin. Lucie performs necromancy and revives Jesse. Grace breaks free from her mother, smashing a mirror. James confesses his love to Cordelia, admitting he never truly loved Grace. Their moment is interrupted when Grace arrives and throws herself into James’s arms.

Cordelia, heartbroken, runs to Matthew Fairchild, who confesses his own love for her and proposes they escape to Paris. James discovers Cordelia has left and sees Lucie has run away with Malcolm Fade. James chooses to stay behind to search for Lucie.

The epilogue reveals Tatiana Blackthorn escaping the Adamant Citadel with a piece of adamas. She meets Belial on a volcanic plain, gives him the key to the Iron Tombs, and he teleports them away.
