Jena Osman’s sixth book, Motion Studies, is a hybrid work consisting of three essay-poems, reaching into the past and a hypothetical dystopian future to offer us urgent warnings about the present: the ubiquity of surveillance technologies, the reduction of the human being to a constellation of data points, and our often-unconscious participation in our own subjugation to these larger forces. True to its title, Motion Studies is a restless book, rarely content to exist in one mode for very long.
