How can we help young people become champions of environmental ethics? The fantastic journey narrated in this formation novel (Bildungsroman) provides some stimulating input for an unusual and creative approach to the matter. In the company of the magic cat Mozot, the two protagonists - Martina and Leonardo - embark on an out-of-this-world journey to the "Feline Hyperuranium." Like a modern-day counsellor, Mozot evokes the youngsters' potential by leading them through fantastic adventures and difficult trials, and manages to lift them from a state of sadness and pre-adolescent insecurity to one of self-awareness and serenity. Retracing the milestones of Thinking throughout History, this upward journey contributes to the two young protagonists' maturing process, while enriching their historical, artistic and philosophical culture. The book contains over 150 links to online resources, for additional insight into formative and educational topics. For this reason the novel straddles the border between fiction and non-fiction, and is recommended for interactive use in a scholastic context. (EDUTAINMENT) The journey ends in a "Feline Paradise" where the cat of the philosopher Giordano Bruno, like a latter-day Virgil, acts as a guide for the two children. By teaching them to become the "Voice of Nature," to speak up for the rights of all living beings who have no voice, he charges the young people - who have yet to develop their ideals - with a veritable 'mission'. With its surprising dramatic turns, cultural references, metaphors, and allegorical figures traceable to the complex psychological sphere, this novel is also suitable for an adult public, inspiring occasions for reflection to share with their children and grandchildren. Note: this work is particularly suitable for being transformed into a live-action/ animated film, possibly divided into episodes.
