Peter Sacks traverses morally charged landscapes in poems reminiscent of Rilke and Celan. Through the lens of Peter Sacks's actual journey from a strife-torn South Africa to a haunted and spiritually frayed America, Necessity travels from remembered heights unblemished by time's weight, through deserts laden by the debris of our mad dreams--progress, conquest, salvation--to arrive at the waters of communal memory, values, and love.
