Early life Edit
Around this time, her father had an affair, later finding out when she was thirteen and keeping it a secret from most everyone since then.
She was about nine years old when Jace Wayland was adopted into their family. Hearing from her mother that Jace had witnessed the death of his own father, she had expected the thin ten year-old boy to 'come to her tearfully' for comfort and advice, liking the feeling of being wanted. Instead, he seemed to not need anyone and seemed self-possessed, which was why it took Isabelle longer to warm up to Jace, while Alec was immediately delighted with him. Even at ten years old he’d had a sharp, defensive wit and an acidic temperament which, in fact, reminded Isabelle of herself. In the end it was Shadowhunting they had bonded over—a shared love of sharp-edged weapons, gleaming seraph blades, the painful pleasure of burning Marks, the thought-numbing swiftness of battle. She eventually felt that she loved him as a brother, especially when Jace insists upon bringing her along with him and Alec on their hunting trips.
The Mortal Instruments Edit
City of Bones Edit
Isabelle is first introduced when trying to seduce an Eidolon demon into following her into a supply room. The demon, oblivious to the fact that she is Nephilim as her runes are covered with the long sleeves of her white gown, follows her inside.
When Clary Fray later follows Jace and Alec into the supply room in pursuit of the demon, Clary stops Jace from killing the demon, therefore distracting him and giving ther demon an opportunity to escape. Isabelle, blaming her, ties Clary's wrists with her whip, which she is disgusted by Clary and amuses her by saying to her " stupid mundie girl" . She then asks Jace what to do with her, and Jace replies to her saying let her go. Isabelle gives him a strong angry look, but lets her go.
Clary later meets Isabelle again when she wakes up in the Institute after being attacked by a Ravener demon. She tells Alec that mundanes die easy and that she first thought that she was a pixie but realized she wasn't pretty enough to be one, and that Jace hasn't visited her yet for three days since he brought her here, not knowing that Clary was coming to her senses. They also talk about the Silent Brothers, with Isabelle saying that she is creeped out by them because they mutilate themselves. When Clary begins to move awake, she stays with Clary as Alec goes off to tell Hodge Starkweather, their tutor. She gives Clary Hodge's blended herbal tea and lends her some of her old clothes that are too long for Clary. She is also slightly amazed about how she was able to kill a Ravener demon, still assuming that she was a mundane. She also tells her a bit about Jace.
When Jace and Clary bring Simon Lewis into the Institute with them, their cat, Church, brings them to Isabelle who rebukes Jace for bringing another mundane, knowing that Hodge will do the same. Simon is immediately attracted to Isabelle. They walk in on her making soup with weird ingredients and, when Jace insults her cooking, she is infuriated for a split second before he takes it back. She seems eager to give everyone the soup she has just cooked and Simon volunteers to try and leaves Jace amused. On their way to the library Jace tells Simon that Isabelle will break his heart as soon as she gets sick of him. She later comes back telling her that dinner was ready but Hodge and Jace try to tell Isabelle that they were both very full. She then tells them that she chucked the soup she was making in the bin and orderd chinese they are both excited and happy and storm out of the room . Once they finish dinner Isabelle then wakes up Clary from her sleep and says that she needs to go to Magnus Banes party to retreive her memory. Isabelle lendes her clothes and does her hair for her while Clary finally tell Isabelle that she knows Alec is a homosexual. Isabelle tells her not to tell anyone or he will get kicked out.
She is present at Magnus's party and when they try to save Simon from the vampires and when they break out to war. Isabelle is also present when Clary remembers where her mother hid the Mortal Cup and goes along with the group to Clary's apartment to retrieve it.
When Alec gets hurt from a demon attack Isabelle stayed behind at the Institute while Jace, Luke, and Clary go meet Valentine.

Izzy also goes to the Faerie Court along with Clary, Jace, and Simon. She is also present when Clary, Jace, and Raphael bury Simon, nessary for him to become a vampire.
While Jace was being trapped by the Inquistor Izzy protested that Jace wasn't Valentine's pet along with her brother Max. Alec however, lied and said that Jace was evil. Alec did this so the Inquistor didn't suspect him of helping Jace, which he did. At the end of the book the whole Lightwood family, except for Max, goes to help fight Valentine. After the fight Izzy and Alec are put on another fleat ship than Clary and Jace.

Isabelle explains what happened to the Clave at the end of the book.
City of Lost Souls Edit
In the beginning of City of Lost Souls, Isabelle is very anxious about the whereabouts of Jace, since it has been 2 weeks from his abduction by Sebastian. When Alec returns from the Clave meeting and announces the Clave's decision to de-prioritize the search for them, Isabelle is devastated, which leads to their searching on their own.
After Clary "joined" Sebastian and Jace in order to find more about her brother's plan, Isabelle, Alec, Magnus and Simon summoned Azazel, a Greater Demon, hoping that he knows a way of severing the bond between Jace and Sebastian. Their plan however fails, since Azazel having already taken one happy memory from every member of the team, insist on being freed on the world in order to stop Sebastian. The team disagrees and so Magnus dismisses the demon.
With their first plan failed, Isabelle with Jocelyn seek help from the Iron Sisters, the weapon forgers of the Shadowhunters, who inform them that the only way to separate Sebastian from Jace without killing Jace is to use a heavenly sword.
Meanwhile, Isabelle's relationship with Simon is restored with Simon spending some nights with Isabelle telling her stories, even the Star Wars. So when Simon decides to be the one who summons Raziel since he has the Mark of Cain and thus more chances of surving, Isabelle is very worried. Fortunately Simon succeeds and acquires the sword but the Mark of Cain is removed by Raziel, Isabelle relieved tells him that he is no longer cursed.
At the end of the book, Isabelle fights alongside the rest of the Nephilim against Sebastian and his dark army. She survives the battle without any serious injury and returns to the Institute where she and Alec take care of Jace, who is unconscious due to the fact that he was stabbed by Clary in order to separate him and Sebastian. After Jace regains consciousness, the siblings share a very touching moment together.
Isabelle at first shares the Lightwood family's snobbish attitude toward mundanes and Downworlders. However, after meeting Clary and Simon, her attitude towards mundanes begins to change as she befriends them and forms a romantic relationship with Simon. Her distressed reaction when Simon was temporarily transformed into a rat, indicated the superficial relationship she intended to have with Simon would not be easily achieved. Despite maintaining a haughty attitude towards Clary and mundanes, she is seen to be somewhat affected by Clary's words at certain points in the book, suggesting she is not as cold-hearted as she allows others to believe.
Isabelle has a great sense of style and is very fashion conscious. She is also somewhat promiscuous. After the death of her brother, Max, she lies down with Simon, but does not sleep with him. Isabelle is portrayed as vain and narcissistic, but slightly insecure. She is sensitive about her great height and wishes that she were smaller and more delicate like Clary. She is arguably the most mature of the Lightwood children and as such adopts something of a maternal role towards them, even her elder brother, Alec.
Despite her narcissistic attitude, Isabelle is very loyal to her family, particularly Alec. She is one of the few people in the world to be aware of his sexuality and the two are very close. Isabelle also possesses a fiery temper which numerous characters are victims of. In spite of her mature and refined nature, she has a habit of throwing temper tantrums and locking herself in her room when things go wrong, flinging objects at people when they intrude on her solitude. While Clary at first finds Isabelle's abrasive nature disquieting, she soon grows to like her when she comes to know her warm side.
Isabelle is a fiercely loyal friend but is volatile and prone to mood swings. Isabelle is described as very flirtatious. She dates many different boys, especially boys that her parents won't approve of. She later reveals that she does this to draw attention away from her brother Alec, who is gay, so that their parents won't become suspicious of him. This begins to show a much deeper and loving side of her that is often only revealed when around her family. She loves her brothers, being particularly close to Alec, and defends them passionately when threatened. Her brother, Max's, death hit her particularly hard, feeling that she failed him, because she ignored him when he said something was wrong. Her grief led her to skipping his funeral, as she felt that she didn't deserve to go.
Isabelle is later revealed to be cautious when it comes to love. This stems from her mother telling her to never trust men, because they will always hurt her. Though at the time she didn't understand the significance of it, she later revealed that she doesn't know how to truly love, though her passion for Simon certainly seems to be opening her up. She is baffled, looking at her brothers, to see them giving themselves to love. She doesn't understand how they can open themselves up to such sadness.
Isabelle also rather likes cooking, but is not very good at it. Her mother, Maryse, was always a good cook but she never taught Isabelle, fearing that she might be relegated to the kitchen forever, instead of being a great Shadowhunter she eventually grew to be.
Jace once described Isabelle as one of the best Shadowhunters he knew. She loves her life and the fight against demons. She greatly enjoys demon hunting. She is also often the 'bait' for demons that she, Jace, and Alec are hunting. She is a very free-spirited girl that enjoys partying, flirting, and clothes.
Isabelle is also very confident in her looks, this is in stark contrast with her brother Alec who isn't confident in his own skin. She frequently uses her looks to achieve her goals, wielding them in everyday life like she would her whip in a fight.
Physical description Edit
Isabelle is described as gorgeous despite the scars left on her skin from the Shadowhunter runes. She has long, ink-black hair and dark brown-gold flecked eyes that are usually mistaken for black. She shares the same slender eyebrows, pale, high-colored skin as her brother Alec. She is said to greatly resemble her mother, so much that Jocelyn Fray mistook her to be her mother when they first met. She is quite tall, being taller than most boys, and very slim. Despite her looks, Isabelle greatly envied Clary, and other girls like her who were small and petite, in the past; though she is happy with her looks, she felt it a hassle to be taller than most boys.
Isabelle is known to be fashionable and usually wears a dress; Clary once even stated that she never saw Isabelle in anything other than dresses.
Shadowhunter Abilities Edit
All Shadowhunters have some of the angel Raziel's blood in their veins. This gives Shadowhunters the ability to survive having runes marked on their skin.

This was inherited from Cecily Herondale, which she received from her brother Will, who in turn received it from Magnus Bane. It first belonged to Camille Belcourt, who also received it from Magnus.
- Electrum whip: Isabelle uses her trademark silvery-gold whip as a primary choice weapon in battle. The whip was a birthday present from her father when she turned twelve. She has shown a high level of skill and proficiency wielding the weapon.
- Daggers: Isabelle has also been shown to include a pair of daggers in her arsenal.
- Seraph blades: Isabelle once used an angel blade.
Love Interests Edit
Isabelle always had difficulty with commitment. Ever since her mother told her to never trust men she guarded herself from them with a string of lovers that were all troublemakers that would irritate her parents. It took Isabelle a long time to realize how she was affected by her mother's advice. When Simon first came to the Institute, he was immediately starstruck by Isabelle, thinking that he finally found someone that could help him get over Clary. Though at first she shows little interest in him in any way other than flirting, he accompanies Isabelle, her brothers, and Clary to Magnus Bane's party. The two dance together, and Isabelle, though intoxicated, worries about him when he was turned into a rat.
When Simon is attacked by vampires, Isabelle is deeply distressed by it and threatened to kill Raphael if he didn't explain what had happened. Isabelle and her family went on a trip to Idris when Forsaken attacked them. Simon was forced through the Portal and the two of them stayed in Idris together for a short period of time. During Simon's imprisonment in the Gard, Isabelle often brought him blood and signed the card XOXO.
After the death of Isabelle's brother Max, Simon was the only one that she opened up to.
In City of Lost Souls, when Isabelle is unable to sleep Simon helps her, and they talk about Star Wars, though she denies it. She goes to Jordan for advice on how to tell Simon she wants to be with him.
|“||I’ve only ever trusted a few people in my life. Really trusted. My mother, Alec, Jace, and Max. I lost one of them already. Clary’s the only reason I didn’t lose another.||”|

However after Clary finds out about Alec's sexuality and keeps it a secret Isabelle warms up to her just a little. Their relationship during City of Ashes and City of Glass isn't progressing very much since Isabelle believes that Clary is the reason Jace is so miserable.

Alec is Isabelle's brother who is almost two years older than her. Both are very protective of each other.
