[2] Kája Saudek met Macourek in 1960, through Olga Schoberová, a young shopgirl in a Prague's ironmongery.
The cycle was initially inspired by the French comic Barbarella, later adapted to a film by Roger Vadim.
Another characteristic feature of the book is Saudek's processing of the sequences of pictures, similar to film editing.
Ro enables her to visit the world of distant future, full of young and beautiful winged people, who live in peace and love, without wars and armies.
Maniacal general Xeron manages to travel with them, but he doesn't like the optimistic and peaceful vision of future and attempts to prevent it.
