Urgent from the outset, Rebecca Foust's Only insists that the only thing worth writing about is everything. Prompted to confront what she does not know, the speaker lists, "Null. All. What's after death or before." This book scales the cliff-face of adulthood, that paradoxical ascent in which the longer we live the less we know of life, in which we find that each of us is only ourselves and yet delicately interconnected with everyone, everything, else. These candid lyrics ponder our broken political systems, family (dys)function and parenting challenges, divergent and intersecting identities, the complexities of sexuality, natural refuge and climate catastrophe, and in general what it means to be human in a world that sometimes feels as if it is approaching apocalypse. At the ledge of this abyss, however, Foust reminds us of the staggering beauty of life, the legacies of survival in the echoes of care that outlast us: "I came / to the canyon rim and saw // how best to carry you: I let the stone go."
