Jenny Kirk

"Someone brough Kirk her seventh cup of coffee of the day, and Kirk sent him immediately for an eighth. It was shaping up to be that sort of week.""-- Jenny Kirk is having very little luck tracking down a hive of fairies (Book 4: Sent Into Mediochre-Drive)"Jenny Kirk is a former member of the MIPF Special Forces and an informant of Rowan Berry.

Traits
Jenny is a stern middle-aged woman, who is also a fan of Star Trek (hence her chosen name). Her face was injured at some point by Alexander Tanner, so she has a diagonal scar across her right eye and the left side of her mouth. It left her with sight problems and looks like she was torn in two and healed up a little wrongly. In addition to being a former member of the MIPF, having possibly left due to the injury which left her with sight problems, she is also on speaking terms with the leaders of seventeen countries, and can speak four languages without accent, three languages with an accent and has a basic understanding of a further six. She is left-handed.

The Good, The Bad and the Mediochre
Although not explicitly mentioned by name, it is likely that Jenny Kirk is the contact from the MIPF who tells Rowan about the genetic relationship between Isobel Williams and Kiwi Mashuga.

Caught Mediochre-Handed
When Rowan and Charlotte are investigating the disappearance of the MABGov building containing Fervour, Joseph, Dhampinella and others, the two visit Jenny Kirk, Rowan's possibly-favourite contact, for information. She tells them that the only witness to the event was Alexander Tanner and that the emergency system was activated by Fervour himself to imprison everyone he thought may be responsible for the destruction of the Stygian Secure Unit. (For the record, he was entirely wrong about this.) When asked about Tanner's whereabouts, Kirk tells them that he's in custody somewhere but she isn't important enough to know where - she implies that even if she were, she wouldn't care, revealing that it was Tanner who gave her the scar. She is also unable to answer the question of who is actually running things now that Fervour is missing, saying that everyone in the entire MABGov seems to be too busy arguing at the moment to do anything.

Finally, she also reveals that in the meantime, while the MABGov is in chaos, James Chrome has commandeered the remaining MIPF forces to hunt the Floor Theta escapees alongside Mediochre.

Sent into Mediochre-Drive
Kirk is directly contacted by Queen MAB in secret to with orders to lead a team guarding Seven the Devil, after the other Players have already woken up. She is stationed at the Seven Players Visitor Centre with her team, mostly made up of former members of the MIPF or the MABA. There are two people in the team that she has worked with before: one of whom is Uma, and the other is never revealed. On learning that the Sixth Player has disappeared, she gets told that her mission is now to prevent Seven the Devil from reaching the Lost Diary of Ludovico Sola at any cost. As soon as the mission changes, Kirk decides that the easiest way to prevent the Seventh Player from teleporting and getting away from them is to destroy it; she instructs Uma to "tear the thing apart." Unfortunately, Seven the Devil wakes up at that very moment, suppresses Uma's Choromancy, Kirk shoots it between the eyes, achieving nothing, and orders her team to blow it up. But she is too late to prevent it from teleporting.

After the escape of the Folk, Jenny Kirk attends Queen MAB's meeting of her most trusted allies via hologram connection. Kirk's response to being told that the Folk have escaped is to swear under her breath, her face contorting even more than it was already from the scar. Queen MAB orders her to take everyone she can get who can be trusted, comb the region, find the Folk, and find a way to kill them. When Mediochre crashes the meeting and he, Joseph and Queen MAB begin theorising back and forth, Kirk's response is to fold her arms and leave them to it. Kirk points out that since the Folk are drawn by people's knowledge of them, if anyone other than Mediochre had been the one to read Ludovico Sola's lost diary, they wouldn't be in this mess (to his credit, Mediochre does apologise). Later in the meeting, it is decided that Kirk should liaise with the dragons in the Cairngorms to lockdown the region and evacuate any nearby settlements.

After the meeting, Kirk perimeters off the area where the Folk had emerged from, but her thorough search of the area is fruitless aside from a small collection of items with significate iron content, that Charlotte had been carrying at the time that the Folk kidnapped her. Kirk is depicted sitting in the back of a large van at the hub of the operation with the heater on, scowling. Rowan is also in the van with her, since they are pooling their resources and both using all the contacts they have access to. When someone brings Kirk her seventh cup of coffee for the day, Kirk immediately sends him for an eighth. As a Star Trek fan, Kirk, on hearing about the fairies' hivemind, compares them to the Borg.

When Charlotte dances with the Queen of the Fairies, Kirk is at the front of the crowd watching from behind the makeshift cordon, with a Missile Bee launcher trained on the Fairy Queen. To her annoyance, she's not quite able to prevent her hands from shaking a little bit.

Fan Theories

 * Jenny might have left the MIPF due to her poor eyesight after the injury caused by Alexander Tanner. Assuming she is the same MIPF contact mentioned in Book 1, this would place the injury as having happened between Books 1 and 3.
