Four Broken Thrones

Three princes and a princess of the four major races, were all born in the same year, same day, same hour, same minute, same second. Now its time for them to claim a bride or groom in order to fulfill the ritual. And in the same year, same day, same hour, same minute, and same second they will be married.

Freya lives in a world where humans and Faerie alike are forced to live together unless invited to the Faerie Forest where the most important of the magical creatures live.
One important detail to note: The humans and the Fair Folk hate each other, so when human Freya moved into the boarding school with her half-faerie sister, meant for the most powerful magical children you can guess how it went. Not to mention it was not just any magical school-it is one in which the three princes and princess of the magical world will secure a bride or groom from for the traditional legendary ritual.

The ritual you may wonder?
-One in which upon the three princes and princess eighteenth birthday are married and their kingdoms are chosen along with the magic they will inherit. It is meant to prevent the four major races from war and violence, for no king or queen would want to destroy a kingdom their children may one day rule.
Right?

Freya is fine with the life she lives and has come to rest with the fact that because her sister is one of four chosen to rule a Kingdom, in a month she will never see her sister again.
That is until the fourth guardian comes to choose a bride for the last prince. When he comes, everything begins to fall apart and Freya, who's always been silent and collected, begins to uncover a mystery that has left the Faerie Forest scarred and if not prevented could destroy both worlds all together...forever.
