It´s as if her life only began once Moon appeared in it. The desultory copywriting work, the boyfriend, and the want of anything not-Moon quickly fall away when she beholds the idol in concert, where Moon dances as if his movements are creating their own gravitational field; on livestreams, as fans from around the world comment in dozens of languages; even on skincare products endorsed by the wildly popular Korean boyband, of which Moon is the youngest, most luminous member. Seized by ineffable desire, our unnamed narrator begins writing Y/N fanfic-in which you, the reader, insert [Your/Name] and play out an intimate relationship with the unattainable star. Surreal, hilarious, and shrewdly poignant, Y/N is a provocative literary debut about the universal longing for transcendence and the tragic struggle to assert one´s singular story amidst the amnesiac effects of globalization. Esther Yi´s prose unsettles the boundary between high and mass art, exploding our expectations of a novel about "identity" and offering in its place a sui generis picture of the loneliness that afflicts modern life.
