"Ле Мизерable: Козеттің тағдыры"

Cosette (kɔzɛt) is a fictional character in the 1862 novel Les Misérables by Victor Hugo and in the many adaptations of the story for stage, film, and television. Her birth name, Euphrasie, is only mentioned briefly. As the orphaned child of an unmarried mother deserted by her father, Hugo never gives her a surname. In the course of the novel, she is mistakenly identified as Ursule, Lark, or Mademoiselle Lanoire. She is the daughter of Fantine, a working woman who leaves her to be looked after by the Thénardiers, who exploit and victimise her. Rescued by Jean Valjean, who raises Cosette as if she were his own, she grows up in a convent school. She falls in love with Marius Pontmercy, a young lawyer. Valjean's struggle to protect her while disguising his past drives much of the plot until he recognizes "that this child had a right to know life before renouncing it"—and he must allow her romantic attachment to Marius to blossom.

Euphrasie, nicknamed Cosette by her mother, is the illegitimate daughter of Fantine and Félix Tholomyès, a rich student. She is born in Paris c. 1815 – c. no. Tholomyès abandons Fantine, who leaves three year old Cosette with the Thénardiers at their inn in Montfermeil, paying them to care for her child while she works in the city of Montreuil sur Mer. Unbeknownst to Fantine, the Thénardiers abuse Cosette while she is under their care. They beat and starve her and force her to perform heavy labor in the inn. Under the Thénardiers' care she is described as "thin and pale", wears rags for clothing, and has chilblains on her hands as well as bruised and reddened skin. She is forced to go barefoot in winter. The narrator also says that "fear was spread all over her". While Fantine is in the hospital, the mayor of Montreuil sur Mer—Jean Valjean masquerading as "Madeleine" to avoid revealing that he is a paroled convict—vows to retrieve Cosette for her. Although Fantine dies before seeing her daughter, Valjean becomes determined to look after the young girl. When he arrives in Montfermeil on Christmas Eve, Valjean finds Cosette fetching a pail of water and accompanies her back to the inn, where he witnesses her mistreatment by the Thénardiers as well as the unkindnesses of their daughters Éponine and Azelma. Valjean leaves the inn and returns with an expensive new doll which he offers to Cosette. At first reluctant, Cosette joyfully accepts it, which infuriates Thénardier; Éponine and Azelma become jealous. The next morning, Christmas Day, Valjean informs the Thénardiers that he has come to take Cosette with him. Madame Thénardier immediately agrees but Thénardier pretends affection for Cosette and acts reluctant. Valjean pays 1500 francs to settle Fantine's debts and leaves with Cosette. Thénardier tries to swindle more money out of Valjean by saying that he has changed his mind and wants Cosette back, informing Valjean that Cosette's mother had entrusted her to his care and he cannot release her without a note from her mother. Valjean, agreeing with him, hands him a letter signed by Fantine. Thénardier then attempts to order Valjean to return Cosette or to pay a thousand crowns, but Valjean ignores him and leaves with Cosette.

Valjean takes Cosette to Paris, where they lodge at Gorbeau House; Valjean begins her education. When Inspector Javert discovers Valjean's whereabouts, he and Cosette must flee. Valjean climbs over a wall and they find themselves in a garden attached to a convent. The gardener Fauchelevent recognizes Valjean as the man who rescued him years earlier and agrees to shelter them. Valjean poses as Fauchelevent's brother and says he is Cosette's grandfather. They live peacefully in the convent for many years as Valjean works with Fauchelevent and Cosette attends the convent school. Over time, she appears to have no recollection of her childhood before arriving at the convent. As Cosette matures, beautiful and healthy, with chestnut hair, beautiful eyes, rosy cheeks, pale skin, and a radiant smile, Valjean realizes it would be unfair to allow her to become a nun without having experienced the outside world which a cloistered nun must renounce. In a later chapter, Cosette eventually remembers her childhood—praying for the mother she never knew; the two ugly Thénardiers, and fetching them water somewhere "very far from Paris". In the same chapter, she asks Valjean about her mother, but he does not answer her question. When Cosette has a dream about her mother as an angel, she remarks that her mother must have been a saint. Valjean replies, "through martyrdom".

Marius sees Cosette for the first time in the Luxembourg Garden. She is fourteen years old, and fresh out of the convent, so he pays little attention to her. After a few months, Marius notices her and sees that she has grown to be an extremely beautiful young woman. Soon Cosette and Marius exchange glances and fall in love. Valjean notices how attentive Marius is to their movements. When he learns that Marius has followed them home and inquired about them, he quickly moves to a more obscure address with Cosette. Marius spots Cosette again during a charitable visit she and Valjean make to the Thénardiers at Gorbeau House, directly next door to Marius. He asks Éponine to find her address for him, and she reluctantly agrees. After many weeks, Éponine takes Marius to Cosette's new address in order to please Marius. Marius watches Cosette for a few nights before approaching her. When Cosette and Marius finally meet again in the garden, they confess their mutual love, share their first kiss, and introduce themselves. They continue to meet in secret. Éponine prevents Thénardier, Patron Minette and Brujon from robbing Valjean and Cosette's house. The same night, Cosette informs Marius that she and Valjean will be departing for England soon. This news devastates them both, because it will mean the end of their relationship. Marius briefly attempts to obtain money and permission to marry from his grandfather to circumvent this issue. Their discussion dissolves into a heated argument stemming from the grandfather's suggestion to "Make her [his] mistress", and Marius storms out. The next day, Éponine (now dressed as a boy) finds Valjean in an embankment in the Champ de Mars and anonymously throws him a note, which tells him to "move". Valjean considers this in horror for a few days, then informs Cosette they will move to their other house and will be in England in a week. Cosette quickly writes a letter to Marius with this information. She catches sight of Éponine through the gate and asks the "workman" to deliver the letter to Marius. Éponine accepts the letter, but does not deliver it. Several nights later, Marius is led to the barricades by Éponine, in hope that they will die together. After being fatally shot, Éponine reveals this to Marius and gives him Cosette’s letter before she dies. Marius writes a farewell letter to Cosette, which is delivered to Valjean by Gavroche. Valjean reads Marius’ farewell letter and decides to follow Marius to the barricades. After the battle is over, he takes Marius' unconscious body through the sewers. After, quite literally, dragging Marius through quicksand in the sewer, Valjean finally manages to get Marius through the sewers alive. He is let out by Thénardier, who has a government key and does not recognize him, simply assuming him to be an assassin who killed Marius. At the exit, he is confronted by Javert, who had pursued Thénardier there and was watching the exit in hopes of catching him. Javert helps Valjean return Marius to his grandfather's house, and Valjean requests to be brought home to say goodbye to Cosette before being sent back to the galleys. Javert allows it, and when Valjean instinctively looks out the window, Javert is gone. It is later revealed that Valjean sparing Javert's life at the barricade had caused a moral paradox and that Javert had committed suicide by jumping into the Seine. After Marius' six month recovery from his wounds, he is reunited with Cosette.

On February 16, 1833, Marius and Cosette marry. The next morning, Valjean tells Marius of his criminal past. Marius asks him to leave him and Cosette. He then allows Valjean to visit her each evening, but makes those visits increasingly difficult until Valjean stops coming. While Marius, assuming the worst about Valjean's character, searches for the real origin of Cosette's money, Valjean loses the will to live and becomes bedridden. When Marius learns from Thénardier that he owes his life to Valjean, Marius and Cosette go to Valjean, find him on his deathbed, and reconcile with him. As Marius looks on, Valjean tells Cosette the story of her mother Fantine and how he came to be her guardian. Valjean dies peacefully.

Critics have often considered Cosette to be something of an empty figure, with no real independent character apart from the role she plays in the lives of others: as an innocent, hopeless child victim to be exploited (for the Thénardiers); a daughter to be protected (for Fantine and Valjean); and an object of adoration (for Marius). Stephanie Barbé Hammer writes that "Having served her function as a paternalizing figure, Cosette grows up into a silent, beautiful cipher". She has the same, but reverse, role as an object of jealousy and hatred for the villainous characters. As Kathryn M. Grossman remarks, she brings out the "hatred of humanity" that is typical of Hugo's villains. When Madame Thénardier sees that the grown up Cosette has become a "well off and radiant young woman, Madame Thénardier responds viscerally, 'I'd like to kick open her belly'." Cosette is also portrayed as largely sexless. Mario Vargas Llosa says of her relationship to Marius,

Now the love between these two is completely ethereal; the sex drive has been surgically removed so that their relationship can be purely one of feeling. Before the wedding the young people exchange one kiss, which is not repeated because, as the narrator says, neither Marius nor Cosette was aware of the existence of carnal desire The dialogue between these two virtuous lovers is as unreal as their amorous behavior. For this reason, the episodes where the two lovers talk to each other are the most artificial moments in the novel. However, in a novel of symbolism and metaphor, Cosette may also be seen as a symbol of hope in the world of Les Misérables, representing the rise of the oppressed and abused from darkness to a bright future. She is the primary motivation for several characters in the novel to lift themselves out of darkness, regardless of whether or not they succeed. For this reason the picture of her sweeping the inn in the evening is often the image most associated as being singularly representative of the main themes of the book, and is used frequently on the cover. Cosette can be seen as a strong female lead in the novel, aiming to achieve happiness ultimately in her life. Ultimately, with Marius, she succeeds in doing so. She can be seen as restrained by the time in which she lived, but still full of hopeful innocence and subtle strength.

Since the original publication of Les Misérables in 1862, the character of Cosette has been included in many adaptations in various media, including books, films, musicals, plays and games, most notably in the 2007 anime Les Misérables: Shōjo Cosette, in which she rather than Valjean is the central character.
