Genevieve Sachenberg is the sixteen year old princes of Kamelot, a new kingdom founded after the destruction of the world we know now. The kingdom, named after the castle of king Arthur by Genenvieve's great-grandmother, seems peaceful, yet Gen doesn't enjoy her life. Being a daughter and not a son of the king suppresses her from being herself: a girl who wants to run around and be free living her life.
When her best friend Calaya arrives for a visit, they discover the biggest secret of Gen's family. And even more secrets seem to arrise from the surface, also some of herself (that include a very handsome prince from Gashû). A web of secret starts to build around her and loyalty is being tested to the maximum. And eventually she must make the most important decision of all: what is more important? The needs of the people or her own desires?
