A Crown of the Gods - S. M. Gaither - Bog

Gods have fallen.
A queen is rising.
And the world will never be the same.
The highest throne in the Kethran Empire lies vacant, its once-ruler now a god-ascending, bringing more chaos and darkness to an already chaotic world. The line between the divine and mortal realms is blurring. The battlefield is set. A final, devastating war is on the horizon.
Casia Greythorne has finally come home to claim the throne that is rightfully hers-one that she hopes she can use to unite her empire and help it survive a war with the very gods themselves. But to take hold of her crown, she'll have to wrestle it free of a past that she's avoided for too long. One that is far more complicated than she realized.

The answers she needs to win her war-and save her world-all lie within that past.
But reaching them might destroy any hope she has of a future.
