City of Glass


City of Glass is the third book in The Mortal Instruments series, an urban fantasy series set in New York written by Cassandra Clare.[1] It was originally published in the United States in hardcover on March 24, 2009.


Picking up from City of Ashes, City of Glass begins a few days after Clary and Simon's awkward break-up. Magnus Bane creates a portal to send the Lightwoods, Jace, Clary and Madeleine, a friend of Jocelyn Fray, to Alicante. Desperate to keep Clary safe, Jace lures Simon to the Institute and asks him to lie to the Lightwoods about Clary not wanting to go to Idris. Their argument over the issue is interrupted when the Institute is attacked by the Forsaken. During the attack, Madeleine is killed. Simon is seriously injured, which leaves Jace with no choice but to bring him through the portal as well or risk the Forsaken killing him.

Magnus explains to Clary what has happened. Clary creates a portal leading to Alicante. Luke attempts to stop her, but instead, both are dragged through to Idris. They land in Lake Lyn, a strange lake with odd reflective powers, which is the very lake that Raziel emerged from with the Mortal Cup and Sword, offering the instruments to Jonathan Shadowhunter (the first of the Shadowhunters). Lake Lyn has been cursed for all Shadowhunters since; if the toxic water is ingested, it causes intense hallucinations, fever, and madness.

On their way to Alicante, Clary starts hallucinating because of the lake water. When they are in the city, Clary collapses and Luke carries her to the home of a Shadowhunter known as Amatis, Luke's sister. Amatis nurses Clary back to health.

Meanwhile, the others are introduced to Aline Penhallow and her cousin Sebastian Verlac. Some members of the Clave want Simon to lie and say that he, along with the Lightwood family, are Valentine's spies, but Simon refuses, which leads to his imprisonment.

Clary sneaks away from Amatis' house to find the others, only to find Jace and Aline kissing each other. Jace yells at Clary to drive her away. Clary leaves, heartbroken, and Sebastian offers to take her home, where she finds an angry Amatis waiting for her.

The next day, Clary and Sebastian go to Ragnor Fell's house, where Clary is shocked to discover that Ragnor has been killed and that Magnus is there in his place. Magnus freezes Sebastian and informs Clary that she must gain a spellbook in the Wayland country home in order to save her mother. After unfreezing Sebastian, Clary and Sebastian leave and travel to the ruins of Fairchild manor, where she and Sebastian share a kiss that she breaks due to it not feeling right. She thinks about Jace throughout the whole kiss. Sebastian informs Clary that Simon is in jail.

Clary returns to Amatis' house where Jace is waiting for her. He apologizes to her for his harsh words, only for the two to fight once again about him not telling her about Simon being in jail. After they calm down, they travel through a portal Clary made to the Wayland manor and get the spellbook only to discover the remains of an experiment Valentine had been running on a half-dead angel. They then learn through the angel that Jace has demon blood. Jace, after the angel shows them these visions, hands a dagger to the angel, who then kills himself.

The two leave the house as it begins to explode and share a brief moment of passion. Clary stops when things begin to go too far, accusing Jace of using her so he can hate himself when he says he blames his demon blood for his incestuous feelings for her. The two return to Alicante and find it in flames. Meanwhile, Isabelle saves Aline from being grabbed by a demon and Aline runs off. Alec goes after her only to find Magnus, where they resolve their relationship. Clary gives the spellbook to Magnus so he can wake her mother.

Jace, Clary, and Alec break Simon and Simon's cellmate, Samuel out of jail, only to discover that Samuel is actually Hodge. He informs them that the Mirror, the last of the Mortal Instruments, is actually the Lake Lyn. Hodge is then killed by Sebastian, who claims that he did it to keep them out of danger. The four realize that Sebastian is a spy for Valentine, and Sebastian flees.

Jace, Clary, Alec, and Simon return to the Hall, only to discover that Sebastian has killed Max (Alec and Isabelle's younger brother). After Max's funeral, Jace sneaks into Clary's bedroom and tells her he loves her and always will. The two then fall asleep holding hands. The following morning, Jace leaves a note behind and sneaks off to find Sebastian.

Clary manages to convince the Clave to fight together with the Downworlders and teaches them a binding rune so they can share their powers, which the dying angel showed her. While the Shadowhunters and Downworlders are forming their alliances with the rune, Alec kisses Magnus in front of the huge crowd, revealing his sexuality to his parents and the Clave.

It is during this time that Clary discovers, after talking with her mother (who had finally awoken from the spell that Magnus used from the spell book) that she had received angel’s blood while in the womb. She also learns that Jace is actually the son of Stephen Herondale, grandson of the last Inquisitor, and Jace had also received angel's blood while he was in his mother's womb. This means that Jace and Clary are not siblings and Jace does not have demon blood, but rather more angel's blood, and further reveals that Sebastian is actually the one with demon's blood and Clary's brother.

Clary marks Simon with the Mark of Cain, a powerful protection spell, with the intent of saving him from Raphael, who says that vampires will only fight with Shadowhunters against Valentine if they give him Simon. The exchange causes the vampires to fight with the Clave.

Meanwhile, Jace finds Sebastian talking to Valentine, who intends to use Lake Lyn to summon Raziel and get a wish that he will use to destroy all the Shadowhunters that are not his allies. After Valentine leaves, Jace battles Sebastian, who informs him of the actual familial bonds that Jocelyn told Clary. Jace defeats Sebastian with a stab through the back, piercing his heart.

Clary portals to Lake Lyn to stop Valentine from summoning Raziel, but Valentine uses a special rune to paralyze her body and voice. He then reveals to her his intent of using her as a sacrifice. When Jace arrives to rescue her, Valentine uses Jace's blood for the sacrifice by stabbing him in the chest and successfully summons Raziel. However, Raziel sees through Valentine's schemes and kills him. When Raziel sees that Clary is the one who deserves one wish, as she wrote her name in the sand in place of Valentine's, Clary asks for Jace back.

During the following celebrations, Clary sees a woman dressed in white talking to Magnus. The Seelie Queen asks Clary for a favor, but she turns the Queen down, stating she has everything she wants. She then returns to Jace, her family, and the rest of her friends to enjoy the fireworks display.
