Helena has no idea, but her life, and that of her three best friends ─Orilo, Eli and Ricardete─, is about to change forever. Elementum, the most terrible villain ever faced by mankind, has started a robbery of planetary dimensions that only they can stop. In different amazing places, from Silicon Valley to Rio Tinto (the corner of Earth most like Mars), the four boys will try to stop Elementum with the strength of their friendship, the power of the periodic table, science and the occasional surprise help.
Join them in this adventure of surprising consequences!
