In BEAST, Frances Justine Post explores the destruction and eventual reclaiming of the self following loss. Many of the poems make up a series of "self-portraits" that explore the psychological core of intimacy with its inherent devotion and betrayal, reward and punishment. In one, she is a wolf; in another, an equestrian and her horse; then a tornado, the dropped crumbs of a beloved, a pack of hounds, and finally a cannibal. The self changes form and species and switches from one voice to multiple voices. Each poem attempts to reinvent the self and alter it as a way of trying to understand what remains after devastation.
