Rain of Shadows and Endings - Melissa K Roehrich - Bog

A world the gods forgot.
Of all the worlds and life they created, the gods favored their children the most. But with that favor came the fear that their Legacy would one day become too powerful and overthrow them. Devram was created. A realm hidden amongst the stars. The gods gave their Legacy the best of all the worlds, and then they left, a sworn agreement to never return and to never interfere.
A historical event.
Forced to a life of servitude, the Fae are required to provide for the Legacy in more ways than one. Every five years, the eligible Fae are gathered for the Selection and assigned to serve in one of the six Kingdoms. To be chosen as the personal Source for a Kingdom Heir is the greatest honor, and for the first time in a millennia, all six Kingdoms have heirs choosing a Source. But their selections could tip the power balance a little too far.
A chosen that was never meant to be.
Tessalyn Asura was as forgotten as the realm. But when she finds herself the personal Source to the Heir of Endings, she winds up serving in the darkest Kingdom of them all . The secrets within the Arius Kingdom are meant to be learned and kept, but this was never the life she wanted. Fighting not only the fate thrust upon her, but the temptation to lose herself to desire, Tessa will do anything to escape her new destiny. Until she starts to realize maybe their world wasn't as forgotten as they thought, and maybe she's the reason why.
