A Crown of the Gods by S.M. Gaither — book slip

The throne of the Kethran Empire lies empty, its ruler now a god bringing darkness and chaos to the world. As the line between the divine and mortal realms blurs, a final, devastating war looms.

Casia Greythorne is ready to claim her place on the throne, unite the empire, and stand against the gods themselves.

But to save her world and the people she loves, she must confront her past and uncover the secrets hidden within it, even if it means sacrificing her hope for a future.
