Book excerpt: Billy Collins has emerged as the most beloved American poet since Robert Frost, garnering critical acclaim and broad popular appeal. Annie Proulx admits, "I have never before felt possessive about a poet, but I am fiercely glad that Billy Collins is ours." This special, limited edition celebrates Billy Collins's years as U.S. Poet Laureate. Questions About Angels--one of the books that helped establish and secure his reputation and popularity during the 1990s--is remarkable for its wry, inquisitive voice and its sheer imaginative range. Edward Hirsch selected this classic book for the National Poetry Series, and each of Collins's poems-from his meditation on forgetfulness to his musings on the behavior of angels-is an exploration of imaginative possibilities. Whether reading him for the first time or the fiftieth, this collector's edition is a must-have for anyone interested in the poet the New York Times calls simply "the real thing."
