Marguerite de la Rocque: The Unbroken Survivor of Isola

Overview of Marguerite de la Rocque

Marguerite de la Rocque, the protagonist of Allegra Goodman’s Isola, is a sixteenth-century noblewoman who transforms from an orphaned heiress into a survivor of extreme isolation and loss. Born the night her mother died, Marguerite grows up in near solitude, raised by her nurse Damienne in a remote château. Her guardian, Jean-François de la Rocque de Roberval, treats her as property rather than kin, ultimately marooning her on an island in the Gulf of Saint Lawrence. Marguerite’s journey is one of physical endurance, emotional resilience, and the reclamation of her own story. She survives two years alone, grapples with despair, and returns to France to establish a school for poor girls, asserting her independence and agency in a world that sought to silence her.

Plot Role and Significance

Marguerite serves as both the central character and the narrator of Isola. Her story drives the novel’s exploration of survival, female agency, and the power of storytelling. The prologue shows her stranded, shouting for rescue as ships sail away, establishing her as a figure of endurance. Throughout the narrative, Marguerite moves from passive victimhood—controlled by Roberval, betrayed by servants, and denied her inheritance—to active agent. She makes critical decisions, from secretly writing letters to confronting Queen Marguerite of Navarre. Her arc culminates in the founding of a school, which represents her transformation from a girl defined by loss to a woman who creates a legacy of learning and fearlessness.

The novel’s structure, with Marguerite as narrator, allows readers to experience her inner thoughts, fears, and determination. Her voice is direct and unflinching, even when describing her darkest moments. By the end, she refuses to let others define her, correcting the Queen’s romanticized version of events. This act of reclaiming her narrative is central to her character’s significance.

Motivations and Traits Shown Through Actions

Motivations

Marguerite’s primary motivations evolve over the course of the story. Initially, she craves connection and autonomy—she longs for friends like Claire, resents Roberval’s control, and secretly studies music and navigation. After her marooning, her motivation shifts to raw survival: she must find food, shelter, and meaning in complete isolation. Later, she seeks justice and truth, refusing to accept the false story Roberval tells the Queen. Finally, she is driven by a desire to empower other girls through education, turning her trauma into purpose.

Key Traits

Resilience: Marguerite endures two years on a barren island, loses her husband Auguste, her infant child, and her servant. She fights off bears and despair, drawing on faith and memory to persist.
Resourcefulness: She learns to hunt, fish, and navigate using the stars. On the fishing boat back to France, she calms a grieving crew by leading a prayer, showing her ability to adapt and lead.
Defiance: Even as a child, she questions authority—she bribes servants for information, sneaks out to see the ocean, and writes letters to seek rescue. She never fully submits to Roberval, even when he physically assaults her.
Empathy: Despite her own suffering, she uses her reward from the Queen to secure a dowry for Claire and found a school, prioritizing others’ futures.
Honesty: When Queen Marguerite reads her sanitized version, Marguerite cannot bear the lies and speaks her own painful truth, risking royal displeasure to be heard.

Chronological Arc

Childhood and Confinement (Chapters 1–10)

Marguerite’s early life is marked by loss and isolation. She is raised by Damienne in a remote château, with only her cat and lessons for company. At age nine, Roberval visits for the first time, coldly inspecting her and showing her a cabinet of gold coins that he denies her. She longs for education and companionship. When she befriends the tutor’s daughter Claire, she experiences genuine connection. But Roberval sells her estate without her knowledge and forces her to sail with him to New France. She begs to stay, but he insists she will belong to him.

Voyage and Marooning (Chapters 11–22)

Aboard ship, Marguerite begins a secret affair with Auguste, a secretary in Roberval’s employ. Roberval discovers their relationship and maroons them on an island, along with Damienne. Auguste dies, as does her infant child, and then Damienne. Marguerite is left utterly alone. She describes her struggle to find food, fight off bears, and maintain her sanity. She relies on psalms and memories to keep from succumbing to despair.

Return to France (Chapters 35–37)

After two years, Basque fishermen rescue her. She pays them with the few coins she had, and they sail to La Rochelle. Once in France, she faces new challenges: poverty, homelessness, and the cold indifference of Roberval’s associates. She sleeps in a church and walks alone to Périgord, suffering blisters and harassment. She is reunited with Claire, who recognizes her by the ring Marguerite had given her.

Court and Reclamation (Chapters 40–42)

Marguerite arrives at the Montfort château just as Queen Marguerite de Navarre visits. Roberval tries to intimidate her, claiming he has already told the Queen her story. In a private audience, the Queen reads her version, which paints Roberval as merciful and Marguerite as a passive victim. Marguerite cannot accept this. She contradicts the Queen, telling the truth of her abandonment, losses, rage, and despair. Moved by her honesty, the Queen offers a reward. Marguerite asks for a dowry for Claire and proposes a school for poor girls. The Queen grants a silver casket of gold and promises a charter.

Marguerite returns to plan the school. Claire refuses the convent dowry and chooses to teach instead. They depart for Nontron, and Marguerite envisions a school where she will teach fearlessness by telling her own story.

Relationships

Roberval (Guardian)

Roberval is Marguerite’s antagonist. He controls her inheritance, forces her onto the ship, and maroons her. He alternates between fake kindness and cruelty, physically twisting her arms during music lessons. He sells her estate, refuses her requests to stay, and later tries to control her story by telling the Queen his version. Marguerite fears and hates him, but she also learns to resist him. Their final confrontation at court shows her newfound power: she refuses to be silenced and tells her own truth.

Damienne (Nurse)

Damienne is Marguerite’s caretaker and emotional anchor. She tries to protect her from Roberval’s harshness, but she is also helpless against his authority. When they are marooned, Damienne dies, leaving Marguerite alone. Her death deepens Marguerite’s grief and isolation.

Auguste (Lover)

Auguste is the secretary with whom Marguerite has an affair. He loves her and tries to reassure her, saying, “You can’t lose me because you have me already.” But he dies on the island, leaving Marguerite to face survival alone. His loss is a devastating blow, but his memory gives her strength.

Claire (Friend)

Claire is Marguerite’s closest friend from childhood. They share clothes, secrets, and lessons. When Roberval forces Marguerite to leave, Claire gives her a ring and promises to meet again. Marguerite initially feels betrayed by Claire’s secret planning, but later, when they reunite, their bond renews. Marguerite uses her reward to secure a dowry for Claire, who ultimately chooses to stay and teach alongside Marguerite.

Queen Marguerite de Navarre (Patron)

The Queen initially believes Roberval’s account and writes a sanitized version of Marguerite’s story. But when Marguerite courageously corrects her, the Queen is moved and grants her the means to found a school. The Queen represents both institutional power and the possibility of being heard.

Key Decisions and Consequences

Writing a desperate letter for rescue: Marguerite writes to a captain, giving the letter to a servant. The servant betrays her to Roberval, who confronts her and forces her to sail. This decision hastens her journey to the New World but also reveals her resourcefulness.
Choosing to survive after losses: After Auguste, her child, and Damienne die, Marguerite considers giving up. Instead, she fights to live, saying she will not let Roberval win. This decision leads to her eventual rescue.
Contradicting the Queen: When the Queen reads her fictionalized story, Marguerite could remain silent and accept royal favor. Instead, she insists on telling the truth about Roberval’s cruelty and her own suffering. The Queen respects her honesty, granting her more than she asked.
Asking for a school instead of personal wealth: Marguerite could have requested money or a husband. Instead, she chooses to create a legacy that helps other girls. This decision transforms her from victim to creator.
