In this fiercely musical, highly anticipated debut release from Half Mystic Press, Melissa Atkinson Mercer interrogates the width, weight, and wholeness of depression, calling out to a self reflected back as monster, as myth, as song and water and tongue. Knock asks us to consider the complications of gender and voice: who gets to speak, who gets listened to, whose stories turn to fact and whose to fiction. Unflinching and tender, this book reminds us what it takes to navigate the mind’s dark seas and come out alive.
