When twelve-year-old Arianna learns that an asteroid is on course to destroy Earth, panic spreads across the world.
But when the moment of impact arrives, something far stranger happens.
Drawn together by the impossible event, Arianna and the other girls who witnessed it soon discover the asteroid was never meant to bring destruction. It was a message. A sign meant for them.
Gifted with extraordinary powers and bound to a purpose far greater than themselves, the girls uncover a hidden world beyond Earth - where ancient forces shape the balance of the universe. But when one of their own is taken... the truth becomes clear: a powerful enemy is rising, determined to claim the source of their abilities.
To save their friend, the girls must journey through strange realms filled with dangerous creatures, powerful allies, and secrets older than the world itself.
Because the asteroid was only the beginning... And if they fail, the fate of the universe will be at stake.
