Divided Island is the story of a woman with a neurological disorder. The day she goes in for the encephalogram that will lead to her diagnosis, she finds herself splitting in two. One of the two women she becomes decides to travel to an island to take her own life; the other remains behind. Scenes and images real and imagined gradually coalesce into the story of a life told from a singular location: a way of perceiving and describing the world, guided by cerebral dysrhythmia. Written in scraps and fragmented chapters, Divided Island is a nonlinear narrative best read as a poetic experience, in which the protagonist's memories and dreams recompose the world and, in doing so, trouble the very notion of the self.

This slim volume makes it abundantly clear why Daniela Tarazona belongs in the company of other Sor Juana winners like Valeria Luiselli, Cristina Rivera Garza, and Almudena Grandes.
