Operación rescate (Aventura total 4)

For millions of years, Eternia was a free planet. But Councilor Fiotto usurped power, banished the king, and turned Queen Runa into a tyrant who enslaved the Eternians. Millions of kilometers from Eternia, Lia and Ulysses signed up for Total Adventure, an elective course taught by Professor Hache, because they had no other choice. What Ulysses and Lia don't know is that their destiny is to help the Eternians, nor that, aboard the spaceship Serendip, piloted by the robot Roxlo, they will travel to Eternia to experience a grand adventure. A true Total Adventure. In this fourth book, all Ulysses and Lia want is to return to Eternia to rescue Roxlo. The problem is that Professor Hache has been tinkering with the ship for weeks, and it seems the repairs will take a long time. Until one day, Lia can't take it anymore, boards the ship, and sets course for Eternia, dragging Ulysses along with her. But what they don't realize is that, after a somewhat impromptu landing, a long and arduous journey awaits them. Eternia is full of surprises!
