A fierce winter storm, prophesied of old, heralds the birth of seven special girls. Born on separate continents, into very different circumstances, they all share one thing: mysterious, ball-like devices, which find their way into each of the girls' possession. The devices' origin and purpose are unknown, but in their seventh year, the girls each experience their power awakening and these devices propel each of them into new and strange realities. It becomes apparent that their destinies are entwined and they each hold the power to mould and shape not only their future, but that of the world and beyond. But their intertwined destinies bring not only gifts but challenges, which slowly unfold over millennia, to reveal their ultimate quest and purpose. Will they fulfill this or will they be distracted by the illusions of their own reality?
