|“||My biggest secret is you.||”|
Johnny Rook was a mysterious figure who ran a booth at the Los Angeles Shadow Market.
Johnny was a Shadowhunter who belonged to the "lost" Herondale line originating from Tobias Herondale—particularly, through his son with Eva Blackthorn. For some reason, he developed a fear or dislike of Shadowhunters and their ways and kept his nature a secret.
When he was a teenager, Johnny opened a booth at the Shadow Market in Los Angeles. Initially dismissed, he was soon accepted into the fold for his determination and uncanny knack for gathering information. For most of his life, his business revolved around being a reliable informant, giving away whispers and rumors to anyone who asked—at a price. He was assumed to be a Sighted mundane by his patrons and colleagues at the Market, an assumption he eagerly supported to hide his true identity.
Johnny's main goal in life was to hide and keep his son, Kit, safe and hidden—particularly from the Nephilim. As an extra measure for protection, Johnny provided his services to the anonymous Guardian in return for money and the warlock's help in installing wards around his house. With his connections, he was able to constantly hide his and Kit's identities, barely using their real names and even having his name legally changed several times.
At one point, Johnny involved himself in sorcery. Additionally, because he was not selective when it came to whom he had business with, he had connections with most species and dealt even with faeries. In light of the Cold Peace, this put Rook on the Clave's watch list and outside their protection; officially, no Shadowhunter should be in business with him.

- Julian: "The sigils of Hell? There's some middle ground between Hell and Heaven, surely."
- Rook: "There's all the world. It's a messy place, Shadowhunter, and we don't all get to keep our hands clean."

One of his many regular customers was Emma Carstairs, a Shadowhunter. Emma often employed his services to aid in her investigation into her parents' mysterious deaths. He gave her information and potential leads and, in August 2012, he was instructed by the Guardian to tell Emma to look into the mundanes and faeries killed and left in the same manner as Emma's parents five years prior.
Once, the Guardian gave Johnny a batch of Atropa belladonna to distill. He kept the leftovers, and when the Centurion Diego Rosales came to his stall, he gave him arrows laced with the poisonous compound, knowing that the plant was illegal and could get him in trouble, simply because Downworlders and Market-goers generally disliked Centurions. The arrows later fatally injured Julian Blackthorn, angering Emma.
When Emma and Julian later came to him asking about the Followers and the Lottery, Rook kept up the lies and told them bits about what to expect after the draw. They were interrupted by a noise Kit, whom Johnny hid in the basement as he always did when entertaining clients, made and found him being attacked by Julian's brother Ty. Wanting to keep the Shadowhunters as far from Kit as possible, Johnny furiously sent them away and refused to do any further business with them. He was eventually forced to tell Emma the truth when she threatened to send the Silent Brothers after him.
Rook was killed by Mantid demons in their home when the protection provided by Malcolm wore off, allowing the demons to come through. Kit was saved by Emma, as well as Tessa Gray and Jem Carstairs who managed to track them down, and was left in the care of the Blackthorn family at the Los Angeles Institute.
