¿Un libro de madurez es el que repite los mismos logros que el autor consiguió en textos anteriores o aquel que lo arrastra hasta lo que de modo consabido llamaríamos «borde del precipicio» para que mire lejos y, mientras, se mire a sí mismo? Sea cual fuere la respuesta, todo verdadero libro de madurez sería, o debería ser, un libro a medio camino entre el pasado y el futuro, entre los caminos transitados y los senderos aún por andar. Y éste, Desde fuera, lo es. / A book of maturity is that repeats the same success that he achieved in earlier texts or the one who drags up what is known so called 'edge of the precipice ""to look far and, meanwhile, will look to itself? Whatever the answer, any real book of maturity would, or should be, a book halfway between past and future, between the roads and paths travelled still to go. And this, from outside, it is. A book, moreover, also of poetic fusion of seemingly discordant views of the recent Spanish poetry, one of whose voices are more personal is undoubtedly that of Alvaro Valverde. A book that knows to be both, if the reader wants to reach the center of what is truly important and not their rhetoric, ""essentialist"" and ""existentialist"".
