The poems of Pablo Neruda published in this book were found during the exhaustive cataloging of all the poet's existing manuscripts and typescripts that began in 2011. They are written in notebooks, on the back page of a music program, or at sea, on the ship's menu, even at an altitude of thousands of meters, destined for Rio de Janeiro. Twenty-one exceptional poems about love, which have not been included in the published works and are seeing the light for the first time, an excellent opportunity to enjoy Pablo Neruda, one of the greatest poets of all time, as we have never read him before. These poems constitute the greatest discovery in Spanish letters in recent years. The immense importance of this unpublished work lies in the fact that they belong to a period starting from the early 1950s and extending until shortly before the poet's death in 1973. They are, therefore, later than Canto General (1950) and were written during the maturity of Pablo Neruda. This edition, commented on by the director of the library and archive of the Pablo Neruda Foundation, Darío Oses, includes photographic reproduction of the originals of many poems.
