Aspira and Eldin live in a perfect world. Sustained by three fountains that bring beauty, prosperity, and protection. What could be wrong? But this visage put up by the Rulers of their planet, Furati, soon comes crumbling down when Aspira is made their Successor. Set to take over for the Rulers one day and struggling to control a strange power, Aspira has to know what the truth is and everything that is going on behind the scenes. As the only one on her planet who has experienced a death in the family, she knows there are things that go wrong. But what is the evil that the Rulers have brought upon them and are trying to hide? And can she right it?
Eldin, brought to the same academy that Aspira attends, is struggling to remember anything, but he knows two things: he has to find as much information on the fountains as possible even if that means using the Successor, and he will do anything to regain his memories. And he soon suspects that he was much more before he came here. And it seems more and more every day, that that someone is not good, but if only he could remember.
As the Rulers continue to threaten them both and they try to keep under the radar, Aspira and Eldin work hard to discover the truth, one that maybe wasn't meant to be uncovered. Because once the truth is out, will it help them or only hurt their world more?
