In One River, A Thousand Voices, Claudia Castro Luna, fresh from her two-year travels as Washington State Poet Laureate, offers us a journey through Columbia River country that is both an exploration of that life-giving watershed and a mythic journey through the flora and fauna, geologies and histories, the various literal and figurative rivers that emotionally and physically have compelled, compel, and will compel the lives of so many creatures and, of course, our frail, ephemeral lives. Castro Luna’s poem is presented as an accordion book, the words cascading down the pages alongside a blue-ink stream evoking the powerful Columbia.
