Victoria, the protagonist, faces her most difficult challenges yet, not just against external enemies, but regarding her own identity. Meanwhile, the character arc of Kirtash remains one of the most compelling aspects of the series. In Panteón , the tension between his nature as a cold, calculating shek and his human connection to the Resistance is pushed to the breaking point. The book forces characters to confront their creators—the gods themselves—raising questions about free will versus divine design.

As the title suggests, memory plays a crucial role. The characters must decide whether to preserve the memory of Idhún or reshape it. Gallego weaves a melancholic tone about exile and nostalgia that elevates the book beyond typical YA fantasy.

In "Panteon," Garcia escalates the stakes for Nerea, introducing new characters and plot twists that significantly impact the narrative's trajectory. The protagonist faces her darkest moments yet, testing her courage, wit, and the bonds of friendship and love that have been central to her journey thus far.
