Two stories intersect in the book: a pseudo-personal one and a completely imaginative one that could be summarized with the definition of paranormal thriller.
In the story, the past resurfaces in the present, bringing back feelings of hate and love. Friendship and loyalty are the keywords but suspense is the queen and where everything is contrary to everything, where the discovery of a mysterious diary will allow three boys to learn about an incredible story, in which a couple of detectives, for succeeding in solving an apparently unsolvable case, will have to cross the boundaries of logic and irrationality.
