Never does Nicole Sky, ordinary Earth girl, dream that the golden pocket watch she discovers one hot summer day will change her life forever. But suddenly, Nicole finds herself on a hostile alien planet and in the midst of a war with the vicious and merciless Omenra. With the help of newfound friends, Lily of planet Lunara, Arli of Azimar, and Diu of the Airioth rebel faction, she tries to return to Earth-until Diu reveals the Omenras' fatal plans. Gavaron, tyrant of the Omenra, has a new weapon with the power to obliterate worlds. His next target: a planet called Earth. All that can stop him is a legend and the Galactera-the galaxy watch-wrought in ancient times by a race long-perished. Chosen by fate, guided by destiny, and driven by a prophecy in which she does not believe, Nicole must embark upon a perilous journey, ally with a dangerous force, and unravel the secrets of the Galactera to find a way back home. Can she save Earth? Or will she destroy it?
