Mark Doty has always felt haunted by Walt Whitman's perennially new American voice, and by his equally radical claims about body and soul. In What Is the Grass, Doty effortlessly blends biography, criticism, and memoir to keep company with Whitman and his Leaves of Grass, tracing the resonances between his own experience and the legendary poet's life and work.

Mark Doty is the author of more than ten volumes of poetry and three memoirs. His many honors include the National Book Award and a Whiting Writers' Award. He is a Distinguished Professor at Rutgers University and lives in New York City.
