With a precise and visceral style, Daniela Tarazona presents the clinical course of a radical mutation - a change whose physiological symptoms emerge from a more intimate evolution. After the death of her mother, Irma decides to take a plane and hole up on a faraway beach. Through the course of her grief, the protagonist's body, her instincts, and her perception, begin to experience a transformation as unexpected as it is natural. The skin over her joints become thick and scaly, her eyes take on a yellow gleam, and she spends more and more time bathing in the hot sun. In these pages, Tarazona manages to address the perennial literary theme of metamorphosis, without relying on simple fantasy or didactic symbolism. More than a fable or a supernatural diversion, The Animal on the Rock is a profoundly biological and introspective novel with universal resonances.
