Query: A masterful book, by a worthy poet

This century Ecuador has given the world many great poets, like Jorge Enrique Adoum and Efrain Jadra Idrovo. But no other Ecuadorian poet has gained as much international fame as Jorge Carrera Andrade, the author of this book. In this book Jorge Carrera Andrade reflects on Spanish-American poetry. No other writer of Latin America is better capable of doing such a thing. Jorge Carrera Andrade examines Spanish-American poetry and all of its meanings, and the book's manner of teaching us about Spanish-American poetry reminds us that he was a professor of Spanish-American literature at the State University of New York at Stony Brook. Since Jorge Carrera Andrade was considered not only Ecuador's finest poet, but one of this century's foremost Spanish-language poets worldwide, it is fair to say that his reflections on Spanish-American poetry are a treasure that we should protect and cherish.
