Like every summer after school, "Petiso" thinks about walking the streets of the Caimancito, his native town, in Jujuy, to look for cardboard to sell and help his mother. Although he knows what is like not having many things, he never lacks love and warm food. However, this summer won't be like others: losing someone and discovering a secret will make him travel by himself to Mar del Plata, secretly, with a backpack and a few bucks in his pockets.

Andrea Braverman, the author, deepens in family ties and the containment we all need to grow up and move on, in a novel filled with emotions and adventure that will touch everyone's heart.
