Skeleton Keys

Rose, an ordinary schoolgirl living alone, encounters the non-human Lucius, who brings her a skeleton key. It is not just any key. This key has the power to unlock doors anywhere in the universe, and Lucius claims that Rose has the right initiative and power to use it. But is it safe? This key seems to have an unknown power of its own, and a dangerous side to its sorcery. As Lucius is instructed to stay with Rose and train her to use her abilities, they end up unlocking all sorts of doors; but are they the right ones? In this unexplainable world of fantasy, great mysteries are about to be solved, and great events are about to happen.
