SPOILER WARNING: Plot details follow. Caution is advised!

Christopher "Kit" Rook, born Christopher Jonathan Herondale, is a Shadowhunter who was raised as a mundane, previously unaware of his heritage. He is the son of the man who called himself Johnny Rook, both being descendants of the notorious Tobias Herondale and his lost line.


Early life

Kit was raised by his father, Johnny Rook. Unbeknownst to Kit, they come from a long line of Shadowhunters, descended from a secret Herondale line.

Like most Nephilim, he was born with the Sight. When he was young and still going to a mundane school, he saw a pack of werewolves fighting and screamed until the police arrived and saw nothing. From then on, Johnny rarely allowed him out of the house, except to occasionally help out at their booth at the L.A. Shadow Market. Since then, Kit taught himself out of old books and spent his free time playing video games in the basement.

Johnny explained to Kit that they could see the Shadow World because they had the "Gift"—his term for the Sight. For good measure, he instilled in Kit a fear of Shadowhunters by telling him that they kidnapped any person with the Sight under the age of nineteen due to their shortage of warriors since the Dark War.

Growing up, whenever Johnny had to entertain clients in their home, Kit was forced to hide in the basement.


Kit was at the Shadow Market one day in August 2012, in conversation with his friend Wren, when he first noticed Jem Carstairs and Tessa Gray, posing as casual customers but were in fact looking into the Rooks, though he paid them little notice. Just then, the Shadowhunters Emma Carstairs and Cameron Ashdown arrived to seek information from his father, making several people, including Wren, uneasy. Some fled the Market altogether. Kit curiously eavesdropped on the conversation, and Emma noticed him, to his father's dismay. Kit then got scared, remembering his father's exaggerated warnings about Shadowhunters recruiting young, Sighted mundanes.

Later, Emma and her parabatai, Julian Blackthorn, came to their house to question Johnny. While Kit hid in the basement as always, Julian's brother, Ty, saw him. Thinking that Emma and Julian were in danger, Ty attacked Kit and held a knife to his throat, demanding answers. Kit was struck by Ty's beauty and Ty soon realized that he was Johnny's son. Julian, Emma, and Johnny came in shortly after, surprised by Ty's presence. Fearing for Kit's safety, Johnny hastily gave Emma more information and established that he would never help them again.

When Emma killed Malcolm, the wards surrounding the Rook house were destroyed. Mantid demons attacked the house and killed Johnny in the process. Terrified, Kit called Emma for help, and she, along with Jem and Tessa—two people personally invested in the Herondales and who had been searching for his line for years—soon arrived to rescue him. Kit was then taken to the Los Angeles Institute; on the way, they revealed to him his Shadowhunter lineage. Kit was disbelieving throughout, until he was able to confirm it when he was able to open the doors of the Institute—a feat only possible if Shadowhunter blood ran through the person's veins. In shock about everything that just happened, Kit demanded to be left alone in his room, while Ty sat outside the door of his room.[1] For a while even after this, Ty continued sleeping in front of Kit's room.[2]


Kit eventually left the room, with thoughts of stealing valuables from the Institute and running away, but never actually went through with any of his attempts. At one point, the famous Jace Herondale came to the Institute, wanting to meet the newly-discovered Herondale, and convinced Kit to try being a Shadowhunter for a week before deciding he didn't want it. Before Jace and his girlfriend Clary left, they spent some time in the Institute training room. Clary then gave Kit a Herondale ring.

Under their tutor Diana's orders, Julian and Kit went to the Shadow Market to find a warlock who could make medicine for Arthur Blackthorn. Initially excited to return somewhere he was comfortable, he was upset to learn that he was no longer welcome there, sent away by the Market's landlord Barnabas Hale. In frustration and anger at Malcolm, Kit punched a Followers of the Guardian sign at the Market, causing his knuckles to bleed. Though he refused Julian's offer to give him a healing rune—his first rune ever—he accepted Ty's offer to Mark him.

Over the next few days, Kit found himself tagging along with the twins Ty and Livvy, who casually included him in everything they did, making them somewhat of a team.

He gradually became more comfortable with the idea of being a Shadowhunter while growing closer to Ty. Kit also kissed Livvy upon her request, as she wanted to know what a kiss felt like, though it meant nothing to either of them.

Kit, Ty, and Livvy discovered that Zara Dearborn, one of the visiting Centurions, was plotting to help her father take over the Institute from Arthur Blackthorn. He joined them in alerting Arthur to this fact, only to find out that Julian had been running the Institute all along. Kit also experienced his first real battle, after the first one at his old house with Johnny, when the Institute was attacked by Malcolm. Kit Portaled to London with the Blackthorns to stay in the Institute there. Kit continued his bonding with Ty and Livvy, and even received a Voyance rune from Ty, which allowed him to see the ghost of Jessamine Lovelace, who told them where Malcolm used to live.

Kit later visited Blackthorn Hall with Ty and Livvy and found an aletheia crystal. He suggested travelling to the local Shadow Market for help, though their trip ended in disaster when the trio were attacked by the denizens of the Market and had to be saved by Magnus Bane after Livvy got hurt.

After the binding between Cristina Rosales and Mark was discovered, Kit went to fetch ingredients with Ty and Livvy, unaware that the Seven Riders had been sent after them. They were attacked by three of the Riders, but Gwyn ap Nudd and Diana Wrayburn intervened. Kit fought the Riders at the London Institute when they attacked it and was recognized by one of the Riders, who claimed to know his face.

Kit was also present at the Council meeting when Annabel Blackthorn was interrogated using the Mortal Sword and went mad, killing Robert Lightwood and Livvy.[2]

Personality and traits

Like many Herondales before him, Kit is sharp-witted and tends to be sarcastic, especially when he gets uncomfortable or anxious.[2] He can also be quite confident, particularly in circumstances where he is comfortable, such as the Shadow Market.[1][2]

Kit also gets some traits that he learned from his dad. He is persuasive, able to convince others to get his way. As taught by his father to be watchful and to study people so that he can figure out whether they can be tricked, what they are about, and what makes the person tick, Kit became very observant, picking out details easily.

Kit is unconsciously eager to please. He attempts to live up to his father's ideals despite the fact that his father is not around to praise him anymore. He also tries hard to please Ty and Livvy, such as getting a permanent rune when Ty asked him to and trying to show both of the twins his skills in the London Shadow Market.

Kit also has some traits of kleptomania, attempting to steal from the Los Angeles Institute and thinking of stealing from the London Institute. Despite this, he is usually trying to steal in order to pursue his goals of running away. He is also quite restless, not liking the feeling of being trapped.[2]

Initially, he resented his Shadowhunter bloodline and tried to push it away, but he eventually came to accept it and became proud of it his lineage. He also goes from being distant from the Blackthorns, to caring for the Blackthorns; he feels like wherever the Blackthorns are, he is home.

Physical description

Kit has blond hair and blue eyes, traits typical among Herondales.

Skills and abilities

  • Nephilim physiology: Being Nephilim, Kit possesses a variety of enhanced physical and mental abilities granted to him by the angel blood of Raziel in his veins and also by the angelic Marks of the Gray Book. This includes enhanced strength, speed, agility, stamina, and coordination, which continue to improve over time and practice.
    • The Sight: As a Shadowhunter, Kit naturally possessed the Sight and is able to see through most magical illusions and layers of glamour over reality. His Sight was further strengthened by his years among the Downworld it the Shadow Market, allowing him to penetrate glamour and enchantments even Shadowhunters cannot immediately see. When he received his Voyance rune, Kit's innate Herondale ability to see ghosts was awakened.[2]
    • Runic magic: Due to the angel blood in their veins, all Shadowhunters are able to apply runes on their skin without any real danger. These Marks, in turn, give varied effects that serve to benefit the wearer.
    • Use of heavenly weapons: As a Shadowhunter, Kit is also able to perform tasks unique to their species, such as the ability to use and call on the power of angels for their seraph blades, as well as to handle any heavenly weapons or objects with effect, which would normally not work for other species. In particular, these are tools made of adamas and forged by Iron Sisters.
  • Natural fighting skills: Despite receiving little formal training, Kit possesses good instincts and reflexes due to his true Shadowhunter nature and is able to handle himself in a battle.

Tiberius was one of the first among the Blackthorns to try for Kit. He slept in front of Kit's door, and together with his sister Livvy tried to integrate him into his family. Ty quickly tells Kit that he's "Sherlock Holmes" himself, and wants Kit as his "Watson." In fact, they later call each other out of fun Sherlock and Watson. Kit can handle Tiberius' mental health a lot better because he grew up with mundanes and saw them like him (in fact, he tells Julian he thinks Mark is weirder). Later, when Kit is injured, he accepts Ty's healing rune, though he denied Julian when he wanted to apply a healing rune to him. Tiberius's main concern is to make Kit a true shadowhunter. He gets his first permanent rune from him to give him "The Sight," and just before the battle against the sea demons, Ty has entrusted him with a seraph blade. In London, Livia is injured in a Shadow Market operation and Kit wears it, which is a big vote of confidence from Tiberius. Later, when Tiberius finds a secret portal to the hiding place of Malcolm and Annabell, he takes Kit with him instead of his sister, meaning he already trusts him very well. And Kit, who initially wanted to flee the institute with stolen weapons, eventually decides to stay with the Blackthorns because he already cares about Ty and Livia. The three of them later approach each other so closely that it is mentioned that even Magnus and Mark see them as one team.

Livia also tries to get Kit, though not as much as Ty. Kit and Livia share their first kiss, although they are not in love with each other. Livia just wanted to do it because she wanted to have that experience, and among the shadowhunters only her family knows, yet she liked it. And it was nice for Kit, too, because for the first time he felt there was someone who cared about him. Shortly after the kiss he describes himself for the first time as "a Herondale". He and Ty and Livia become a solid team throughout the book, which is even recognized by Mark and Magnus. Eventually, Kit, who actually wanted to escape, stays with the Blackthornes, because he already has so much on both of them. Livvy, who notes that Kit and Ty later became friends, tells Kit that a girl named Paige, has treated her brother bad, and asks him to be honest with Ty, whereupon Kit replies that he has nothing else would do.


  • Herondale ring: Kit owns a Herondale ring, given to him by Clary (and Jace who once also owned the ring), which first belonged to James Herondale. Though James wasn't one of Kit's ancestors, like Kit, James was close to the Blackthorns in his life.[2]
