Un cuento acerca de la iniciación en el mundo de la lectura y la escritura, a través de la inspiradora huella que una abuela fuera de serie deja en un niño. Muchas abuelas son soñadoras, escriben poemas, incluso usan sombreros verdes de plumas... pero pocas se atreven a participar en concursos de poesía, implantar la semilla de la literatura en sus nietos y realizarse a través de ellos, haciéndolos crecer y tejer un hilo de continuidad entre las vidas de ambos mediante la escritura. Petunia es la abuela de Vicente, y de loca en realidad tiene muy poco; al contrario, sus extravagancias se ven matizadas por sus genuinos intereses, de modo que no es difícil identificar a nuestras propias abuelas con la que este libro retrata. English Description A story about the introduction to the world of reading and writing, through the inspiring effect that a phenomenal grandmother has on a child. Many grandmas are dreamers, write poems, even wear green feathered hats ... but few dare to participate in poetry contests and plant a love of literature in their grandchildren, and consequently fulfill themselves through them, helping them grow and weaving a strand of continuity through both their lives by way of writing. Petunia is Vicente's grandmother, and she is not actually that crazy; on the contrary, her eccentricities are explained by her genuine interests. In this way, it's not difficult to identify our own grandmothers with the one depicted in this book.
