A Slow Green Sleep takes the long view: from the prehistoric through the human historic and on to the posthistoric. Voices speak out of fresh and ancient graves, from the recent and distant pasts, and from some possible and probable futures. Will the human experiment fail, or change? Can we stop loving the wrongest things, finding beauty instead in self-effacement and the certainty that the earth will live on without us? Can we come to consider other people, and our nonhuman others, as equal in importance to ourselves? The poems in A Slow Green Sleep use various formal strategies to make resting places where one can embrace how the world is with us today, and how it will be hereafter.
