A fan-fiction writer faces college, independence, a tough writing class, and changing relationships, all while deciding if she will write her own story or stay in her fictional world.
Cath Avery arrives at the University of Nebraska-Lincoln, feeling overwhelmed and anxious for her freshman year. Unlike her outgoing twin sister, Wren, Cath is introverted and deeply attached to her comfort zone, which mostly involves the fictional world of Simon Snow. Wren decided they should not room together, saying they needed to grow independently. Cath finds herself in a small dorm room with a seemingly unfriendly roommate, Reagan, and Reagan's always-present, charming boyfriend, Levi. Their first interactions are awkward and tense, with Cath retreating to her laptop and her Simon Snow fan fiction, feeling completely out of place and alone.
Cath enrolls in a fiction writing class taught by Professor Piper. To Cath's dismay, Professor Piper openly dislikes fan fiction, seeing it as unoriginal and a barrier to true creative writing. This immediately creates a conflict for Cath. Her entire writing identity is built around her popular Simon Snow fan fiction, 'Carry On, Simon.' She finds it hard to write original stories, always comparing them to the complex world she has already mastered. This school pressure adds to her already significant worries about college and her place in the 'real' literary world.
Despite initial tension, Reagan slowly starts to help Cath come out of her shell. She insists Cath eat meals with her and Levi. Though Cath is uncomfortable at first, she gradually begins to open up. Levi, especially, is a kind and patient person. He helps Cath with her laundry, walks her to classes, and genuinely tries to understand her love for Simon Snow, even reading parts of 'Carry On, Simon.' This growing friendship gives Cath much-needed support and a sense of belonging outside her online fan community.
While Cath struggles to adjust, Wren quickly embraces the party scene, making new friends and drinking often. Her behavior worries Cath, who often waits up for Wren or tries to ensure her safety. Their father, Art, who has bipolar disorder and is often emotionally fragile, also worries about Wren's choices. This changes their childhood roles, with Cath becoming the more responsible and protective sister, constantly checking on Wren and trying to talk with their father.
As the semester continues, Cath and Levi spend more and more time together. Levi's consistent kindness, his real interest in her writing, and his calm manner contrast sharply with the chaos in Cath's life. He helps her with her English papers, reads her fan fiction aloud, and offers emotional support. Their connection grows beyond friendship, leading to their first kiss and the start of a sweet romantic relationship. Cath falls for Levi, despite her anxieties and the complications of his on-again, off-again relationship with Reagan.
Cath is under great pressure to finish 'Carry On, Simon,' her very popular fan fiction, before the final book in the official Simon Snow series comes out. Her readers eagerly await the ending, and she feels a strong duty to them. This intense fan fiction writing schedule often clashes with her school duties, especially her original fiction assignments for Professor Piper. The stress of balancing her two writing worlds, along with her family drama and new relationship, pushes Cath to her limits. She questions her priorities.
Wren's excessive partying leads to her getting alcohol poisoning and needing hospitalization. This event is a wake-up call for both Wren and their father. Cath rushes to be by Wren's side, showing the deep bond they still share despite their recent distance. The crisis forces their father, Art, to face his own mental health and get help. It brings the family closer, allowing them to discuss their mother's abandonment and its lasting effects on their lives more openly and honestly.
After much struggle and delay, Cath finally writes an original short story for Professor Piper's class. Using her own life and worries for inspiration, she creates a raw and honest piece. To her surprise and relief, Professor Piper praises her work, recognizing her talent for storytelling even outside of fan fiction. This validation is a major turning point for Cath. It boosts her confidence and makes her realize that her writing skills are useful and valuable on their own.
After Wren's hospitalization, the twins slowly begin to fix their relationship, acknowledging the distance that had grown between them. Wren starts to take her recovery seriously and wants to reconnect with Cath. At the same time, Cath and Levi's relationship becomes stronger. They confess their feelings for each other, and Levi officially breaks up with Reagan, confirming his commitment to Cath. Cath also begins to accept that her fan fiction, 'Carry On, Simon,' is a valid form of creative expression, even as she explores original writing.
Cath successfully finishes 'Carry On, Simon,' bringing her beloved fan fiction to a satisfying end for her millions of readers. This achievement, combined with her school success and personal growth, marks her coming-of-age. She has navigated her first year of college, formed meaningful relationships, and found her own voice as a writer, both within and outside of fandom. Cath ends the year feeling more secure in herself, with a strong relationship with Levi, a mending bond with Wren, and growing confidence in her ability to write her own story, literally and figuratively.

The Mentioned
Laura's character arc is largely in the past, but her actions continue to influence the present lives of the Avery family.
The novel shows Cath's move from adolescence to adulthood. She deals with who she is without her twin sister and her fan fiction identity. College forces her to face her anxieties and build a new identity, separate from the 'Simon Snow girl.' She learns that her love for fan fiction does not stop her from being an original writer or a capable person. This theme is clear in her struggle to write original fiction for Professor Piper, her attempts to make friends outside of Wren, and her eventual understanding that she can embrace both her fan identity and her growing adult self.
““She was a girl who knew how to be a fangirl. She was a girl who knew how to be a twin. She was not a girl who knew how to be alone.””
Fangirl supports fan fiction as a real and powerful form of creativity and community. Cath's 'Carry On, Simon' is not just a hobby; it is her life's work, a source of great pride, connection, and skill. The book argues against the dismissive view of fan fiction, showing how it can lead to original writing and be an important emotional outlet. The online fandom gives Cath a sense of belonging and purpose, validating her voice even when the academic world initially does not. This is clear in Cath's dedication to her story and the passionate responses from her readers.
““What do you mean, 'fanfiction isn't real writing'?””
The lasting effect of family, especially the trauma of their mother leaving, shapes Cath and Wren's lives. Their bond as twins is central. The story explores the challenges of growing up while both holding onto and changing that intense connection. Their father's mental health struggles also highlight the responsibilities and anxieties within the family. The novel shows how family members deal with past wounds in different ways, eventually finding healing and reconnection through shared vulnerability and support, especially after Wren's hospitalization.
““It's not like she abandoned us. She just… went away. She just… wanted to be free.””
The novel shows the growth of a tender, supportive, and healthy first love between Cath and Levi. Their relationship is built on mutual respect, patience, and real understanding. Levi's consistent kindness and his ability to see and appreciate Cath for who she is, including her quirks and anxieties, help her grow. Their dynamic contrasts with Wren's more superficial romantic encounters, showing the importance of emotional connection and trust. Levi actively listens to Cath, helps her with her struggles, and celebrates her successes, creating a safe space for her to be herself.
““I'm not going anywhere, Cath. I'm right here.””
Interweaving excerpts from Cath's fan fiction and the official Simon Snow books.
Throughout the novel, Rainbow Rowell intersperses the main narrative with snippets from Cath's fan fiction, 'Carry On, Simon,' and passages from the original Simon Snow books. This device serves multiple purposes: it immerses the reader in Cath's world and passion, provides context for her writing, and often mirrors or comments on the events and emotions unfolding in Cath's own life. The fantastical elements of Simon Snow act as a foil to Cath's realistic struggles, highlighting her escapism while also demonstrating the depth of her creative engagement.
The contrasting personalities and evolving relationship of identical twin sisters.
The relationship between Cath and Wren is a central plot device. Their identical appearance but vastly different personalities create immediate conflict and opportunities for growth. Their separation at college forces them to define themselves individually, while their deep, shared history provides a constant backdrop of emotional resonance. The twin dynamic explores themes of dependence, independence, and the enduring power of familial bonds, especially when one twin tries to break free while the other clings to the past.
An introverted character placed in a challenging new environment.
Cath's experience as an extremely introverted, socially anxious fan girl thrust into the unfamiliar and overwhelming world of college serves as a classic 'fish out of water' scenario. This device generates much of the initial conflict and humor, as Cath struggles with roommates, classes, and social expectations. It effectively highlights her journey of growth as she slowly adapts, forms new relationships, and learns to navigate an environment far outside her comfort zone, ultimately finding her footing and thriving.
An authority figure who challenges the protagonist's established beliefs.
Professor Piper acts as a mentor figure for Cath, albeit an unconventional one. Her strong stance against fan fiction directly challenges Cath's primary creative outlet and identity. This opposition forces Cath to re-evaluate her writing, push her boundaries, and ultimately discover her capacity for original storytelling. While initially a source of stress, Professor Piper's demanding teaching style and eventual recognition of Cath's talent are crucial catalysts for Cath's artistic and personal development, pushing her toward a broader understanding of what it means to be a writer.
