Scarlet is a 2013 young adult science fiction novel written by American author Marissa Meyer and published by Macmillan Publishers through their subsidiary Feiwel & Friends.

Plot
After the events of the first book, Scarlet Benoit is an 18-year-old girl living on her grandmother's farm in the rural town of Rieux, France. Her grandmother, Michelle, has been missing for two weeks and Scarlet is certain that she had been kidnapped rather than left on her own will or had killed her self, as the authorities believe. While delivering fresh goods to one of her loyal but unfriendly customers, her friend, Émilie Monfort, introduces her to a jittery, shy street fighter whose code name is Wolf, who saves her after she makes a speech defending Linh Cinder, the Lunar cyborg who caused chaos at the Eastern Commonwealth's annual peace ball. She notices a tattoo on his arm; a string of numbers and letters that initially have no meaning to her. When she gets back from her job, her estranged father, Luc, is there and is desperately trying to find something. She questions him, who has burn marks all up his arms from being tortured, and he says that the same people have her grandmother because she was supposedly hiding something. The one clue that he can remember is that the kidnappers had a tattoo on their forearm, similar to Wolf's. Scarlet heads out to question Wolf in a fight ring, where he defeats and almost kills the champion. The next morning Wolf comes by her farm and tells her that the tattoo stands for a group he used to be part of and that they are the ones who had kidnapped her grandmother. He decides to help Scarlet and they both embark on a trip to Paris.
On the train ride to Paris, Scarlet meets a young man called Ran, who Wolf seems to smell on her later. Later, when a Letumosis outbreak occurs on board, they jump off the train and continue their journey through the woods. While resting, Ran shows up and Scarlet realizes that he and Wolf already know each other and don't get along well, and Ran is eventually revealed to be Wolf's younger brother. Wolf fights with Ran and almost kills him until Scarlet shoots him in the arm. They leave Ran unconscious and get on another train to Paris, and Scarlet learns that her father has died. Throughout this time, Wolf and Scarlet start to develop romantic feelings for each other.
Meanwhile, Cinder teams up with Captain Carswell Thorne, a fellow American prisoner who stole a spaceship from the American Republic military, and they escape from New Beijing prison. Cinder passes out while trying to start Thorne's stolen ship up, and Thorne has to reboot her. They escape on the ship, a Rampion, but find problems with the autopilot. Cinder remembers that she has Iko's personality chip and inserts it. Once in space, Thorne asks Cinder where she wants to go and even though Dr. Erland told her to go to Africa, she chooses to go look for Michelle Benoit, a woman connected to the missing Lunar Princess Selene, who happened to be Cinder, and Scarlet's grandmother.
When Scarlet and Wolf arrive in Paris, he leads her to where her grandmother is being held, but turns her in and reveals that he is a Lunar Special Operative, a bioengineered wolf-Lunar hybrid soldier who serves Queen Levana. Glamouring himself as her grandmother, Ran manipulates Scarlet into telling everything she knows about Princess Selene and why her grandma can't be manipulated. She recalls Linh Garan, the man who adopted Cinder after her surgery, talking to her grandmother but doesn't know why she resists manipulation. Then, she is imprisoned.
At the same time, Cinder and Thorne land in Rieux and discover Michelle Benoit's shelter, where Cinder was held in a suspension animation tank for eight years and later turned into a cyborg. They go to Gilles's tavern but are found by the military after tracking her dead stepsister's ID chip, which Cinder still had with her. Trouble gets worse when the Lunar wolf soldiers start attacking, following Queen Levana's order. Barely escaping, Cinder tracks down Scarlet.
