A narrative and poetic experience in which body, memory and delirium clash to recompose the world and, therefore, the identity of the self. Divided Island is the story of a woman with a neurological disorder. The day she goes in for an encephalogram, which will diagnose her cerebral dysrhythmia, 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 and follows the trail of her suicidal other half. Written in brief chapters and fragments, Divided Island is a nonlinear narrative best read as a poetic experience. A collection of scenes, moments, memories, dreams, and images gradually coalesce into the story of a life told from a singular a way of perceiving and describing the world, guided by dysrhythmia. From 2022's recipient of the acclaimed Sor Juana Inés de la Cruz literary prize comes a novel that profoundly explores one woman's grief and fractal experience of the passage of time.
