Football or life - The Invisibles

"The Invisibles" is a young adult series centered around football: the great matches and moments of collective euphoria, plus their behind-the-scenes aspects, what happens in training, in the changing rooms, in the private lives of star players (Hulk, Helton, Cardozo, Saviola, and Liedson appear in the first three stories), and also what happens in their darker and less reputable areas.
The main protagonists are three young "Invisibles" (so-called because they are never seen), one from each of our three biggest clubs (FC Porto, Benfica, and Sporting), who act on behalf of an international organization investigating the secret files of football.
These "Invisibles" are between 14 and 16 years old (when they must give up their place). Their actions are characterized by discretion and effectiveness; their resources are shrewdness, the art of disguise, and the most advanced nanotechnology, namely a dream mobile phone that performs the most improbable functions.
It is certain that this series will deeply resonate with all young football fans. However, given the quality of the plots and how they connect the game with life, integrating aspects of adolescent issues, such as the turbulence of other passions (which often clash with the passion for football), "The Invisibles" is also a series recommended to all reading enthusiasts.
