The Instability of Identity and the Self in Nona the Ninth

The Instability of Identity and the Self in Nona the Ninth: A Thematic Analysis by Tamsyn Muir's Nona the Ninth (2022) is the third volume in the Locked Tomb series, and it is a book that is fundamentally about the question of who a person is when the boundaries of body and soul are porous. The novel's central thematic claim is that identity is not a fixed, essential property of a person, but rather a fragile, contested, and often temporary arrangement of body, soul, and memory. Through the character of Nona, the novel explores how a self can be a composite, a guest in a body that belongs to someone else, and how the very act of loving and being loved can become the only stable anchor in a sea of shifting selves. This analysis will trace this theme across three distinct parts of the plot, examine its connection to key characters and symbols, and address the complexity and contradictions the novel builds into its own argument about the self. The novel's exploration of identity is not abstract; it is grounded in the physical and the mundane. The opening chapter, a guest list for a birthday party transcribed by C. Hect, immediately establishes a world where categories are unstable. The list includes dogs, gang members, teachers, and various figures from the resistance, but it is also a list of people who are not what they seem, and it ends with an entry addressed to three unnamed people. This list, with its careful attention to the details of who is invited and who is not, becomes a metaphor for the novel's larger concern: who gets to be a person, and who gets to be included in the circle of the self? The list is a way of trying to fix identity, to pin it down, but the novel will show that such attempts are always provisional. The thematic claim is that identity is a process, not a state of being, and that the process is often violent, painful, and incomplete. The novel asks not just who a person is, but what a person is, and it suggests that the answer is always in flux, dependent on the bodies we inhabit, the souls we carry, and the memories we hold or lose. This is a story where a soul can be a stranger in a body, where two people can merge into a new being, and where a god can consume the souls of billions and still not be whole. The instability of the self is not a flaw in the system; it is the system itself. ## Tracing the Theme Across the Plot ### Part One: Nona's Daily Life and the Body as a Borrowed Vessel The first part of the novel establishes the theme through Nona's daily life in the city, where she lives with Camilla Hect, Pyrrha Dve, and Palamedes, who is inhabiting Camilla's body. The novel immediately tells us that Nona is not simply a person, but probably one of two people, and that her body belongs to one of them. This is not a metaphor; it is a literal fact of the world. Nona's body is a vessel, and her soul is a guest. The evidence of this is in her eyes, which are a deep, warm gold, a color that Palamedes explains is a sign that a soul is in someone else's body. The novel uses eye color as a soul marker, a physical sign of the instability of the self. Nona's identity is further destabilized by her lack of memory. She does not know who she was before she woke up in this body, and she is told that she is probably one of two people. This uncertainty is the foundation of her daily life. She is a person who is constantly being observed, with Camilla writing pages of notes on her behavior, and Palamedes trying to figure out who she is. The novel shows that Nona's identity is not something she possesses, but something that is being constructed around her by the people who care for her. They call her Nona because the first thing she said was
