The book that I want to recommend is El Valle de las gigantas of Gustavo Martín Garzo.
I have wanted to recommend it because I read it last year and it seemed to me that it was very entertaining and curious.
The book is about a child, Lázaro, that spends the summer with his grandfather.This summer he will discover amazing things about his deceased grandmother.
Sincerely it is not a book to describe, is a book that you must read
It is a most representative Gustavo's book.
