The Moon Rogue by LMR Clarke

Enemies become friends, and lovers become enemies as the battle lines are drawn in a desperate struggle to save the world from Dark Magic.

Prince Mantos, rightful heir of the Masvam Empire, is murdered to allow Dorai, the Dark Goddess, to seek ultimate power. However, all is not lost, for Mantos has died once before and mysteriously returned from the dead.

Into this tumultuous conflict steps Emmy, a slave who escaped captivity, only to be enslaved once more. Recognized by the healer Rel, who shares Emmy’s unusual skin coloring, as a descendant of the Uloni, a race brought forth into the world by the daughter of gods, Emmy may be the key to returning balance to this world.

The Moon Rogue is a must read for fans of Becky Albertalli, Emily M. Danforth and Leigh Bardugo.
