El libro que conmovió a millones de lectores. < p/> Estimado lector, estimada lectora: < p/> Aunque el uso habitual de un texto como é ste es describir las caracterí sticas de la obra, por una vez nos tomaremos la libertad de hacer una excepció n a la norma establecida. No só lo porque el libro que tienes en tus manos es muy difí cil de definir, sino porque estamos convencidos de que explicar su contenido estropearí a la experiencia de la lectura. Creemos que es importante empezar esta novela sin saber de qué trata. < p/> No obstante, si decides embarcarte en la aventura, debes saber que acompañ ará s a Bruno, un niñ o de nueve añ os, cuando se muda con su familia a una casa junto a una cerca. Cercas como é sa existen en muchos sitios del mundo, só lo deseamos que no te encuentres nunca con una. Por ú ltimo, cabe aclarar que este libro no es só lo para adultos; tambié n lo pueden leer, y serí a recomendable que lo hicieran, niñ os a partir de los trece añ os de edad. --El editor < p/> ENGLISH DESCRIPTION < p/> The book that moved millions of readers. < p/> Dear reader, < p/> Although the usual purpose of a text like this one is to describe what the book is about, we will take the liberty of making an exception to the established norm--just this once. Not only because this book is very difficult to define, but also because we are convinced that explaining its content would impair the reading experience. We believe it is important to begin this novel without knowing what it is about. < p/> However, if you choose to embark on this journey, you should know that you will be accompanying Bruno, a nine-year-old boy, as he moves with his family to a house near a fence. Fences like that one exists in many places around the world--we only hope you never come across one. < p/> Finally, it should be noted that this book is not just for adults; children aged thirteen and older can, and should, read it as well. < p/> The Editor
