"In each of her previous novels and story collections, the Irish author Mary Costello has revealed the inner vastness hidden within even the quietest lives. Her latest book, A Beautiful Loan, goes further, with a faithful, poetic exploration of the multitudes we contain and what it means to be human. . . . the significance and profundity [Costello] renders to each and every life is a measure of her depth of attention, and perhaps why there is no greater chronicler of the inner life at this moment. As artificial intelligence and big tech force an increasingly diminished definition upon us of what it means to be human, this novel reminds us that we are so much more."
