One of Mexico's most successful literary voices presents the world to us anew. "I know that my mind is slow, at least compared to that of standard people." This is what Karen, a young Mexican woman, says. At the beginning of the novel, she is a neglected autistic girl, but under the care of her aunt, she learns to say "I" and to become "I." The sea and her grandfather's tuna factory become her favorite places, and beings with gills are closer to her than "standard people." Yet she has much to offer the latter: ideas, commitment, even profit. But one day, everything is at stake, and even the last connection seems severed like an oxygen hose. Sabina Berman has crafted a stunning, surprising, wild novel. With Karen, we dive deep and discover: it is not humanity that holds the world together at its core.
