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 came 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 Shadow Market. 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, either become uneasy or flee the Market altogether. Kit curiously eavesdropped on the conversation, and Emma noticed him, to his father's dismay. Kit himself 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 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, apparently protecting him.[1]


A few weeks after his arrival at the Institute Kit visited the training room and debated stealing the expensive-looking weapons to sell when he ran away. He stuffed some into his jacket but was interrupted when Jace Herondale appeared to speak with him about his heritage. After noticing the weapons Jace pointed out that Kit may also be in danger from Malcolm's followers, and convinced him to give life at the Institute a week.

Julian later took Kit with him to the Shadow Market. Kit was upset to learn he was no longer welcome there after being asked to leave by Barnabas Hale, as he had planned on running away from the Shadowhunters and opening up a stall at the Market.

Over the next few days Kit started spending time with Ty and his sister Livvy, and became more comfortable with the idea of being a Shadowhunter while growing closer to Ty, who ended up giving Kit his first rune. Kit also kissed Livvy on her request, though it meant nothing to neither of them.

Kit helped Ty and Livvy discover the true nature of the Centurions' visit; to take 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 battle when the Institute was attacked by Malcolm, and travelled 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 discovered an aletheia crystal there. 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 was 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 and they were in danger. 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 seemingly 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, to his and Ty's dismay.[2]

Personality and traits

Kit has some of the same personality traits of the Herondales before him. This is seen in his sarcasm, especially when he gets uncomfortable or anxious.[2] He is also confident, especially 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 Tiberius and Livia, such as getting a permanent rune when Tiberius 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 having a distance to the Blackthorns to caring for the Blackthorns; he feels like wherever the Blackthorns are, he is home.
