Early Life and Death
Mallory Keen was born in Belfast, Ireland to Frigg and an unnamed man. Mallory had a poor relationship with her father due to his alcoholism. On 21 July, 1972, which later became known as Bloody Friday, Loki disguised himself as one of Mallory's friends and tricked her into installing a car bomb on a school bus, claiming that soldiers were onboard instead of children. Her mother, Frigg, knowing Mallory would die, appeared to her disguised as an old hag and convinced her to disarm the bomb, giving her two knives. The car bomb blew up, killing Mallory, but since she died a heroic death with a weapon in her hand, she was taken to Valhalla.
Mallory lives in the Hotel Valhalla, and is Magnus Chase's hall mate. She, along with T.J., Halfborn, and X, invite Magnus to breakfast with them. With icing sugar around her mouth, Mallory reminded Magnus of a reverse-color-scheme Joker. When the group enters battle practice, Mallory stays by Magnus' side until dying from an arrow through the neck.
Mallory and her friends are recruited by Gunilla to help track down Magnus and take him back to Hotel Valhalla. While their attempt to get him in Midgard was failed by Hearth, the group successfully meets them again in Lyngvi. However, she and her hallmates side with Magnus over Gunilla, and aid him in defeating Surt. In the end of the book, she, along with Magnus, Samirah, T.J., Hearthstone, and Blitzen, are complimented by Odin as the true heroes of Valhalla.
Mallory is first seen chasing her new hall mate with her boyfriend Halfborn when they run into Magnus. They search her suite and find the symbol of Loki. Before battle practice, Halfborn was adjusting her armor, much to her annoyance. A murder of ravens come and bring their new hall mate to them. They are shocked that Alex is female, as they were told she was male. They head into battle against the dragons and she covers her hall mates during the mock battle.
At dinner, she sits with her hall mates as they talk about Magnus' dream about Loki. She, T.J., and Halfborn escort Alex back to their corridor after dinner.
During the wedding, Mallory, T.J., Halfborn, Hearth and Blitz fight the giants. Following their victory, they return to Valhalla to celebrate.
Mallory has broken up with Halfborn and is part of the crew preventing Naglfar from launching. She along with her hallmates board Magnus' bright yellow ship and they frantically try to prep the boat and narrowly avoid plunging into the void. She talks with Magnus after his vision of Loki. After picking up Sam and Alex they are dragged underwater by nine women. They surface in a cauldron and are fished out by Aegir. She supports an uncounsous Halfborn and sees Hearth and Blitz are prisoners about to be cooked. She and T.J. support a semi conscious Halfborn while Alex, Sam and Magnus free Hearth and Blitz. Just as they are about to eat one of the sea god'd daughters calls out Magnus. They eventually get Aegir to calm down and convince their host to let them leave, if they can escape his daughters. Mallory drives her knives into one of the maidens and uses them to stay in place. She escapes when Njord arrives and Hearth takes out a wall. When they surface she and the others head below deck to get food while Magnus, Blitz and Hearth speak with Njord.
She talks with Magnus about about the absence of Blitz and Hearth. She insults Halfborn, who is within earshot, before climbing the mast.
When they arrive at York she, Sam and Halfborn watch the ship while Magnus, T.J. and Alex scout out the town. During that time they defend the ship and Halfborn cuts her hair when a water horse grabs hold. She tells Magnus that Loki both tricked her into setting up the car bomb that killed her and into disarming it by giving her the knives.
When Magnus and the others return they are considered because he consumed the blood, but she brushes it off as a temporary boost in his powers. They arrive in Flåm split up to find a train station, she goes with Sam and Magnus while T.J. and Alex go with Halfborn. Within a few minutes she finds the woman who gave her her knives and goes after her. They track her down to the train station and board a train. Sam and Magnus keep her from attacking the woman and they speak with her. She addresses Mallory by her full name and the events that lead to her death. The woman reveals herself as Frigg and reveals that she is Mallory's mother. Mallory is shocked and angered by the revelation and scolds the goddess for not telling her sooner. Frigg gives her daughter a walnut shell and leaves. Mallory jumps out of the window of a moving train and breaks her arm, which Magnus heals. She is still in shock that the queen of Asgard is her mother. Sam talks to her about Odin inspecting her at floor nineteen, as well as sending Alex and Magnus to the floor, and how she is the one who hold them all together. They set out to find the mead and they devise a plan of action. She comes up with a plan to help the thrall by sharpening their scythes with the whetstone. She tricks them into impaling each other and the thre move on. They pry open the doors using her knives and the assistance of Gunlod, the mead keeper's daughter and prisoner. She gives them the mead and her father and uncle return. They agree to let Magnus stay and fight on of the giants while she, getting sucked into the nutshell, is carried by Sam and they take the mead. Luckily, Baugi follows then while Suttung stays behind. She spends the fight in the nutshell and apologizes to T.J. for killing the slaves. They leave Flåm and reach Jotunheim by morning.
The big banana can not get through the ice so they walk to shore. Just as they reach it they are invited in by Skadi to explain themselves. They bath and have a hot meal with the giantess. She tells the group Loki will launch Naglfar by noon the following day.skadi gives them permission to spend the night. In the morning they have breakfast before skiing over to Naglfar.
When they arrive she, Blitz, Hearth, T.J. and Halfborn leave to destroy Loki's forces and give Magnus a better chance during the flyting. Magnus hears her curse in Gaelic from a distance. She hobbles over to the flyting with a broken foot. She watches the match and is concerned for Magnus, but is pleased with his complement towards her. After the flyting she impridond Loki in the walnut. She scoops up the walnut just as the hoard attacks and they make their way to the edge and jump off at Sam's request. They land on the backs of water horses and they get out of the harbor just it is freezing over.
They spend three days at sea. During this time she watches over Loki and becomes closer with Halfborn. They arrive on Vigridr, the battle field they will die on during Ragnorok, and are greeted by the gods. She is embraced by Frigg and hands Loki over to the Aesir. She is given a signed copy of Odin's new autobiography, a feast in her honor and a Turkish bathrobe. When they get back to Valhalla she and Halfborn get back together and throw plates at each other and kiss.
Mallory is described as having green eyes and frizzy red hair. She has a short stature in comparison to her hall mates.
|“||"She's a sweetheart, once you get past the fact that she's a horrible person."||”|
