The poetry of Mercedes Roffe knows how to surround the silence, seduce the readers from an abyss feeling, and dares to skirt the limits in a plural sense. It is a return trip to the genesis and future of every word, a journey whose highest points happen whenever lightning appears. That is, whenever Roffe captures the poetic brilliance of words. She is currently one of the greatest voices in Argentine poetry. Some of the most sensitive aspects of human experiences are included in this ninth book of poems."

Each title introduces readers to one important position in American government, explaining the duties of the office, how someone reaches that office, and famous leaders who have held that office in the past.
