In Penumbra, Kate Behrens' third collection, the poems are linked by themes of dislocation and heredity. If the dead are ever-present here, so is love: the absence of, rewards and longing for it, the endurance and effort of it. We are led from the poet's bohemian childhood to the complex grief, in middle age, that followed the death of her painter father, and on to individual animals, people, and even trees that are differently uprooted or burdened. Everything is haunted here, but the boundaries of death and love are permeable, nature full of revelation.
