The Mortal Instruments is a series of six young adult fantasy novels written by Cassandra Clare, the last of which was published May 27, 2014. The Mortal Instruments is chronologically the third series of a proposed five in The Shadowhunter Chronicles.
1) City Of Bones
When fifteen-year-old Clary Fray heads out to the Pandemonium Club in New York City, she hardly expects to witness a murder — much less a murder committed by three teenagers covered with strange tattoos and brandishing bizarre weapons. Clary knows she should call the police, but it’s hard to explain a murder when the body disappears into thin air and the murderers are invisible to everyone but Clary.
Equally startled by her ability to see them, the murderers explain themselves as Shadowhunters: a secret tribe of warriors dedicated to ridding the earth of demons. Within twenty-four hours, Clary’s mother disappears and Clary herself is almost killed by a grotesque demon. But why would demons be interested in ordinary mundanes like Clary and her mother? And how did Clary suddenly get the Sight? The Shadowhunters would like to know….
2) City Of Ashes
Clary Fray just wishes that her life would go back to normal. But what’s normal when you’re a demon-slaying Shadowhunter, your mother is in a magically induced coma, and you can suddenly see Downworlders like werewolves, vampires, and faeries? If Clary left the world of the Shadowhunters behind, it would mean more time with her best friend, Simon, who’s becoming more than a friend. But the Shadowhunting world isn’t ready to let her go — especially her handsome, infuriating, newfound brother, Jace. And Clary’s only chance to help her mother is to track down rogue Shadowhunter Valentine, who is probably insane, certainly evil — and also her father.
To complicate matters, someone in New York City is murdering Downworlder children. Is Valentine behind the killings — and if he is, what is he trying to do? When the second of the Mortal Instruments, the Soul-Sword, is stolen, the terrifying Inquisitor arrives to investigate and zooms right in on Jace. How can Clary stop Valentine if Jace is willing to betray everything he believes in to help their father?
3) City Of Glass
To save her mother’s life, Clary must travel to the City of Glass, the ancestral home of the Shadowhunters—never mind that entering the city without permission is against the Law, and breaking the Law could mean death. To make things worse, she learns that Jace does not want her there, and Simon has been thrown in prison by the Shadowhunters, who are deeply suspicious of a vampire who can withstand sunlight.
As Clary uncovers more about her family’s past, she finds an ally in mysterious Shadowhunter Sebastian. With Valentine mustering the full force of his power to destroy all Shadowhunters forever, their only chance to defeat him is to fight alongside their eternal enemies. But can Downworlders and Shadowhunters put aside their hatred to work together? While Jace realizes exactly how much he’s willing to risk for Clary, can she harness her newfound powers to help save the Glass City—whatever the cost?
4) City Of Fallen Angels
The Mortal War is over, and sixteen-year-old Clary Fray is back home in New York, excited about all the possibilities before her. She’s training to become a Shadowhunter and to use her unique power. Her mother is getting married to the love of her life. Downworlders and Shadowhunters are at peace at last. And—most importantly of all—she can finally call Jace her boyfriend.
But nothing comes without a price.
Someone is murdering Shadowhunters, provoking tensions between Downworlders and Shadowhunters that could lead to a second, bloody war. Clary’s best friend, Simon, can’t help her—his mother just found out that he’s a vampire, and now he’s homeless. When Jace begins to pull away from her without explaining why, Clary is forced to delve into the heart of a mystery whose solution reveals her worst nightmare: she herself has set in motion a terrible chain of events that could lead to her losing everything she loves. Even Jace.
5) City Of Lost Souls
When Jace and Clary meet again, Clary is horrified to discover that the demon Lilith’s magic has bound her beloved Jace together with her evil brother Sebastian, and that Jace has become a servant of evil. The Clave is out to destroy Sebastian, but there is no way to harm one boy without destroying the other. As Alec, Magnus, Simon, and Isabelle wheedle and bargain with Seelies, demons, and the merciless Iron Sisters to try to save Jace, Clary plays a dangerous game of her own. The price of losing is not just her own life, but Jace’s soul. She’s willing to do anything for Jace, but can she still trust him? Or is he truly lost?
Love. Blood. Betrayal. Revenge. Darkness threatens to claim the Shadowhunters in the harrowing fifth book of the Mortal Instruments series.
6) City Of Heavenly Fire
Darkness has descended on the Shadowhunter world. Chaos and destruction overwhelm the Nephilim as Clary, Jace, Simon, and their friends band together to fight the greatest evil they have ever faced: Clary’s own brother. Sebastian Morgenstern is on the move, systematically turning Shadowhunter against Shadowhunter. Bearing the Infernal Cup, he transforms Shadowhunters into creatures of nightmare, tearing apart families and lovers as the ranks of his Endarkened army swell. Nothing in this world can defeat Sebastian—but if they journey to the realm of demons, they just might have a chance…
