The cover features Tessa holding the Shadowhunters' Codex and wearing the clockwork angel pendant.
Tessa Gray should be happy -- aren't all brides happy? Yet as she prepares for her wedding, a net of shadows begin to tighten around the Shadowhunters of the London Institute. A new demon appears, one linked by blood and secrecy to Mortmain, the man who plans to use his army of pitiless automatons, the Infernal Devices, to destroy the Shadowhunters. Mortmain needs only one last item to complete his plan.
He needs Tessa.
Charlotte Branwell, head of the Institute, is desperate to find Mortmain before he strikes. And Jem and Will , the boys who lay equal claim to Tessa's heart, will do anything to save her. For though Tessa and Jem are engaged, Will is still in love with her.
The last words of a dying Shadowhunter provide the clue that might lead Tessa and her friends to Mortmain. But their small group cannot stand alone, and the powerful Consul doubts that Mortmain is coming. Deserted by allies, the Shadowhunters find themselves trapped when Mortmain seizes the medicine that keeps Jem alive. With his best friend at death's door, Will must risk everything to save the girl they both love.
To buy Will time, the warlock Magnus Bane joins with Henry Branwell to create a device that could help defeat Mortmain. As they all work to save Tessa and the future of the Shadowhunters that resides with her, Tessa realizes that the only person who can save her is herself -- for in the discovery of her own nature, Tessa could become more powerful than she ever dreamed possible. But can a lone girl, even one who can command the power of angels, face down an entire army?
Danger and betrayal, secrets and enchantment, and the tangled thread of love and loss intertwine as the Shadowhunters are pushed to the very brink of destruction in the breathtaking conclusion of The Infernal Devices trilogy.
The prologue opens in York during 1847. Aloysius Starkweather’s granddaughter Adele receives her first Mark from the Silent Brothers, but dies during the process, believed to be due to her frail health. In 1873, Will is practicing knife throwing when Charlotte introduces Jem, the Institute’s new ward. Will is openly hostile and cruel towards Jem due to his sickly appearance, but Jem is not fazed. Jem offers to help Will with his knife throwing, to which he agrees.
In 1878, two months have passed since Will’s sister Cecily has arrived at the Institute, urging Will to contact their parents. Tessa is preparing for her wedding to Jem. Gabriel Lightwood arrives at the Institute claiming that his and Gideon’s father has transformed into a demonic worm. Will, Jem, Tessa, Cecily, Henry, Gideon and Gabriel travel to the Lightwood House to find Benedict has indeed turned. They attack the worm, with Gabriel firing the killing shot with his bow. Immediately after the battle, Jem suffers a violent attack due to his illness.
Back at the Institute, Will discovers that Jem has been taking more of the demonic drug that is keeping him alive and killing him. Angered, Will confronts Jem, but Jem says that he is taking more so that the time he has with Tessa is full. Will searches for more of the drug, but finds it has been all bought, sending him into despair, in which he reveals to Tessa his continued love for her. Jessamine is returned to the Institute, but during the return automatons attack the Institute. Jessamine is killed, and in her dying words tells Will that Mortmain is at Idris, which Cecily believes Cadair Idris, a mountain in Wales. Will looks up to see Jem running back, saying that Tessa was taken, before collapsing.
Will contacts Magnus, asking for his help to find the cure. Jem overhears Magnus talking about Will’s love for Tessa, and confronts him about, revealing that if he had known he would never have proposed to Tessa. During what he believes is his dying wish, Jem asks Will to leave his bedside and go after Tessa. Will agrees, and leaves. After Will has left, Jem asks Charlotte to stop looking for a cure. Will rides towards Cadair Idris. On his first night, Will feels his parabatai bond with Jem snap, causing his parabatai rune to bleed, and realises Jem has died. A pack of werewolves attacks him, but is called off by their leader, Woolsey Scott. Woolsey urges him to keep living to honour Jem’s memory. Will makes a memorial site for Jem, before continuing to search for Tessa.
Tessa is bought to Mortmain, who reveals that she is a warlock, although born between an Unmarked Shadowhunter, Aloysious Starkweather’s true granddaughter, who was kidnapped by faeries at Mortmain’s order, and a Greater Demon. He then forces her to Change into his father. John Shade’s memory gives Mortmain the spell he needs to bind demons to his automatons, in which he succeeds. Will finds Tessa, but is trapped in the same magic cage that she herself is in. Will tells her of Jem’s death, and they both weep for Jem. Afterwards, Will tells her of his feelings, which she reciprocates and the two make love.
Charlotte leads the London Institute Shadowhunters, against the wishes of the Clave, to Cadair Idris, along with Magnus and three Silent Brothers. Enoch, Mical and Zachariah. Magnus finds Tessa and Will and releases them, before leading them to the fight with the automatons. During the battle, Henry’s back is broken and Brother Mical is killed. Brother Zachariah’s hood is knocked back, revealing him to be Jem, much to Will and Tessa’s shock. To end the fight, Tessa taps into the spirit locked in her clockwork angel, Ithurial, and Changes into the angel, killing Mortmain and destroying the automatons, before collapsing.
Charlotte convinces the Silent Brothers to let Jem return to the Institute one last time, to end his relationship with both Tessa and Will, so as to let them all heal. Tessa tells Jem that she loves both him and Will, before agreeing to meet Jem once a year on the bridge where Jem first took her. He then goes to Will, and tells Will that he will find a way to be a Shadowhunter without him. Will then goes to Tessa, and begins reading to her. Over the next few months, both of them begin to heal over the loss of Jem. Will sees Jessamine’s ghost, who says that in death she will protect the Institute, and urges him to propose to Tessa, which he does. Will then honours an agreement he made with Cecily, and visits his parents.
Tessa then talks of the life that she and Will led. She talks of the birth of their children; James and Lucie, the marriage of Gideon to Sophie and Gabriel to Cecily, and their encounters with Jem over the years. In 1937, on Will’s deathbed, Jem, now a fullfledged Silent Brother, returns to the institute plays the violin one last time for Will and Tessa, after which Will dies peacefully. Tessa, still with the appearance of a 20 year old, realises the losses she will have to face with her children and grandchildren, and cuts contact with her family and travels with Magnus to help herself with the loss of Will. Magnus reassures her that the loss gets easier to bear.
In the epilogue, the story flashes forward to 2008, not long before the ending of “City of Heavenly Fire”. Tessa is waiting on the bridge for her yearly encounter with Jem. She turns to see not Brother Zachariah but Jem as he had appeared before changing into a Silent Brother. Jem confesses his enduring love for her, to which Tessa returns. The two then share a kiss.
