A dazzlingly original, shot-in-the-arm of a debut that reveals a young woman's every thought over the course of one deceptively ordinary day, in the formally innovative tradition of Grief Is the Thing with Feathers and Ducks, Newburyport . • "Extraordinary."— The New Yorker She wakes up, goes to work. Watches the clock and checks her phone. But underneath this monotony there's something else going on: something under her skin. Relayed in interweaving columns that chart the feedback loop of memory, the senses, and modern distractions with wit and precision, our narrator becomes increasingly anxious as the day moves on: Is she overusing the heart emoji? Isn't drinking eight glasses of water a day supposed to fix everything? Why is the etiquette of the women's bathroom so fraught? How does she define rape? And why can't she stop scratching? Fiercely moving and slyly profound, little scratch is a defiantly playful look at how our minds function in — and survive the darkest moments.
