Un plan maléfico (Aventura total 2)

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 great adventure. A true Total Adventure. In this second book, Ulysses and Lia are certain: they must return to Eternia at all costs to protect the Eternians from the evil Queen Runa. The problem is that Professor Hache doesn't share their opinion and refuses to put them in danger again. After much persuasion, and thanks to Roxlo's intervention, they manage to convince him and set sail for the strange planet. Once there, they discover that the situation is more serious than they imagined. Will they be able to thwart Runa's evil plans?
