Ada Limón served as the 24th Poet Laureate of the United States. Her latest book, Startlement: New and Selected Poems, is a retrospective spanning two decades and also includes 21 new poems. The book is the poet's invitation to meet the world with an open mind — but also an open heart. She encourages us to embrace our "strangeness" and our tenderness, and to bear witness to the arc of all we know with hope and compassion.
