Fangirl recap

College separates identical twins Cath and Wren for the first time. While Wren pursues parties and independence, anxious Cath retreats into her popular Simon Snow fan fiction until her blunt roommate Reagan, Reagan's friend Levi, classmate Nick, and Professor Piper draw her into a wider life. Family crises complicate the year: their father Art's mental health deteriorates, Wren's drinking ends in hospitalization, and the mother who abandoned them reappears. Cath also learns that collaboration and romance require firmer boundaries when Nick claims their shared work and Levi briefly breaks her trust. She eventually reconciles with Levi and Wren without surrendering her own needs, refuses a forced reunion with her mother, and begins balancing care for her family with college. Cath finishes her fan-fiction epic before the official series finale and completes an original story that wins a university prize, ending the year as both a fan writer and an author increasingly willing to claim her own work.

Identical twins Cath and Wren begin their first year at the University of Nebraska-Lincoln with very different plans. Wren has chosen another roommate because she wants independence; Cath, who expected their old partnership to continue, is placed with the formidable Reagan. Cath avoids the dining hall, speaks little to strangers, and devotes herself to Carry On, Simon, the enormously popular fan-fiction novel she writes online. Reagan's friendly former boyfriend Levi is constantly around their room, while Wren quickly begins attending parties with her roommate Courtney. Cath joins an advanced fiction course taught by Professor Piper and notices Nick, a confident classmate. College makes Cath's existing anxieties sharper, but her writing gives her a community and a structure when ordinary campus life feels unmanageable.

Cath settles into a narrow routine of classes, fan fiction, and occasional meals arranged by Reagan. Nick asks her to meet at the library, and the two begin taking turns extending the same original story. Cath treats the sessions as collaboration, though they never clearly define ownership. Levi continues seeking her company and listens with genuine interest when she reads Simon Snow material aloud. Cath's distant high-school relationship with Abel ends, confirming that it had little emotional substance. Wren, meanwhile, is drinking heavily and dismisses Cath's concern as an attempt to control her. The twins' different approaches to college leave them increasingly estranged, even as Cath begins to form tentative connections beyond her sister.

Cath's growing closeness with Levi leads to a kiss, but she later sees him kissing another girl at a party and feels that she misread both his interest and their relationship. A more serious crisis follows when Art's manic behavior escalates and he is hospitalized. Cath goes home, frightened that leaving for college helped expose him to another breakdown, and considers abandoning the semester to care for him. Wren resists being pulled back into the family's old arrangements and is also more open than Cath to contact from Laura, the mother who left them. In class, Cath submits Simon Snow fan fiction as an assignment. Professor Piper treats it as plagiarism within the course rules and fails the piece, while still insisting that Cath has enough talent to write something original.

Cath tries to remain at home for the next term, but Art refuses to let her make his illness the limit of her own future. Back at school, Levi apologizes and steadily works to regain her trust. Cath eventually accepts that his mistake does not erase their connection, and they begin a real relationship. She visits his family's ranch and enters a busy household unlike her own. Her academic confidence remains fragile: Professor Piper gives her a final chance to complete original fiction, while Nick submits the story he developed with Cath under his name alone and asks for her support. Cath must decide whether keeping peace is worth allowing someone else to erase her contribution.

Wren's pursuit of independence reaches a crisis when severe alcohol poisoning sends her to the hospital. Laura appears there, but Cath refuses to treat the emergency as a simple repair of their long abandonment. Wren finally acknowledges the danger in her drinking, and the sisters begin speaking honestly again rather than trying either to merge their lives or sever them. Cath also asserts herself in the dispute over Nick's manuscript; Professor Piper recognizes that the work was collaborative and will not let Nick benefit from denying Cath's part. With Art recovering and Levi offering support without demanding that she become someone else, Cath returns to the original story she has repeatedly avoided finishing.

Cath completes Left, an original story shaped by separation and the complicated bond between sisters, and it wins a university fiction prize. The achievement does not require her to abandon fan writing: she also finishes Carry On, Simon before the official eighth Simon Snow novel is published, fulfilling her promise to the large readership that has followed her version. Wren resumes college with a more cautious approach to alcohol, and she and Cath restore their closeness while accepting that they need distinct lives. Art is steadier, though his illness remains part of the family's reality; Laura is not forgiven merely for returning during a crisis. Cath and Levi are together, Reagan has become a genuine friend, and Cath ends the year able to claim both her creative work and a place among other people. She shares the arrival of the official Simon Snow ending with Levi rather than retreating from the change it represents.

Cath returns to college after Wren's hospitalization and gradually rebuilds her relationship with her sister, who accepts that her drinking has become dangerous. Cath does not welcome Laura back simply because Laura appears during the crisis, and that estrangement remains unresolved. Art recovers enough to resume work while accepting that his daughters cannot organize their lives entirely around protecting him. Professor Piper pushes Cath to finish an original piece instead of retreating into fan fiction, and Cath's story about separation, Left, wins a university fiction prize. She also ensures that her work on Nick's story is acknowledged. Cath completes Carry On, Simon before the official final Simon Snow novel appears, giving her readers the ending she promised. By the close she and Levi are securely together, Reagan remains her friend, and Cath has found a way to value both her fan community and her own original writing. She reads the newly published Simon Snow finale with Levi, no longer facing change entirely alone.
