The Court of Secrets by Rebecca L. Garcia

Darkness can only survive in the hearts of the wicked.

I was brought back from the edge of death by Morgana so I could reign. But whilst there, something had latched onto me, and it had no plans on leaving. With each passing day, I feel my heart growing darker and it becoming stronger. Struggling to suppress the beast within, I lose myself in the scandals and politics of my kingdom. Caught between the high priest-Vahaga-and the lords of the land, being in power has never seemed more difficult.
The threats of war with Berovia looming on the horizon means I need to remain strong for my people. My coronation nears, but with the mystery surrounding my father’s death coming under scrutiny, being back at court has never been so dangerous. Especially for a queen.
