SynopsisEdit

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.

PlotEdit

work in progress. not advisable for reference purposes as info below is incomplete!

Will trains his sister, Cecily, to become a Shadowhunter. However, he is annoyed at her presence in the London Institute and her insistence that he come home with her, but he does care for her and is fiercely protective of her.

Will discovers that Jem has been taking large doses of Yin Fen to keep him fit, whilst also killing him inside. He travels to buy more of the demon powder, with Cecily who follows him, but discovers that someone has bought it all up.

When Jessamine Lovelace is brought back to the London Institute from the Silent City, the Magister's automatons attack. Will had no wish to see her, so was inside but upon hearing the noise, rushed down to help. He sees Jem run after a carriage of automatons, but does not realize that they have kidnapped Tessa. Jessamine tells him that Mortmain is in 'Idris', before dying of a stab wound in the back. Jem returns because the carriage was too fast and he collapses.

Cecily overhears Will's conversation with Jessamine and figures out that Mortmain is hiding in Cadair Idris, a mountain near where Will used to live in Wales, as she knew Mortmain and his personality.

Will asks Magnus Bane to help them find a cure for Jem, who is dying and running out of Yin Fen. Magnus asks Will if Jem knows that he was in love with Tessa, but he tells Magnus that he did not want to hurt Jem. But Jem overheard and gives Will his blessing to rescue Tessa, instead of him as he is too ill.

On the road to Wales, Will feels his parabatai rune bleeding, and realizes that Jem has died. He throws up and asks Woolsey Scott for advice, even though he got into a fight with some of his werewolf pack. Will cuts his hand with Jem's dagger and buries it in the ground by a tree.

He eventually finds Tessa in Mortmain's hideout, and rushes to her without thinking, causing him to be trapped inside the invisible barrier with Tessa. Believing that Jem was dead and thinking that they would both die, Will confessed everything to Tessa and told her how much he loved her, then they both had sexual intercourse during the night.

The next morning, Tessa wakes up and realizes that her clockwork angel is on his shoulder near his neck, and she pulls it away to find that it had left a mark in the shape of a small white star on Will, thus creating the mark of the Herondales that will be seen on the descendants in the future generations.

Magnus Bane then finds the two and gives a comment regarding what they were doing. Relieved and embarrassed, Will quickly puts on his clothes along with Tessa, and they both follow Magnus to where the others were. The others were fighting hundreds of automatons, and they were losing. Will joined in the battle right away, telling Magnus to keep a watch on Tessa. However, in the gist of the battle, Will finds out that one of the Silent Brothers, Brother Zachariah, was actually Jem, and he was not dead! At the same time, Tessa gets kidnapped again and Mortmain holds her, threatening Will and the other Shadowhunters with her. Tessa Changes into the angel trapped inside or necklace, Ithuriel, leaving Will in awe as he watched her blaze with fire. She kills Mortmain, but she Changes back into herself afterwards and falls to the ground unconscious, making Will very worried. They had won the battle, but once Will returned to the Institute with the others, he entered a state of depression since he was worried about Tessa not regaining consciousness, and feeling lost without Jem. Much to his happiness, Tessa recovers and he had a conversation with Jem, however the conversation with Jem made him a little sadder for a few weeks, but he soon recovered after fighting like he normally would against demons and enduring days without Jem. Will and Tessa grew closer and closer afterwards, until Will finally proposed to her and Tessa said yes. They scheduled to marry when Will turned 18, and he used Henry's Portal to go back to Wales along with Cecily, Tessa, and Gabriel to visit his parents after so long. Will and Cecily have a happy reunion with their parents, and Will announces that Tessa is his fiancee. He has a wonderful time in visiting his parents after 5 years.

Tessa and Will get married and have two children, James and Lucie. It is revealed that Will died at 78 years old in 1937 of old age, and Jem, as Brother Zachariah, visits him on his deathbed and plays to him for one last time before he dies. Tessa is heartbroken when Will dies and begins to travel with Magnus Bane, who understands the grief of out living loved ones. The two part ways in New York where they went because of World War II. Church the cat comes with them and is dropped off at the New York Institute. Later, in 2008, Tessa is meeting Jem on the bridge and we see that Jem has given up the life of a Silent Brother. They reunite and kiss; Tessa invites Jem to travel the world with her. Tessa also recalls the pain of watching Will die and living her family when he realizes how her children, and grandchildren, age while she remains young. She vows to not get close to her descendants.
