Sundered By Fate by Vera Winters

A broken bond. A corrupted court. A shadow threatening everything.

Returning to Astaria as a hero should have been triumphant, but Aric Solarian finds only suspicion and betrayal waiting for him. As magical anomalies tear reality apart and his visions of a tortured Malekith grow more intense, Aric discovers disturbing signs of corruption within the heart of his own realm.
Lord Regent Valerian’s secretive research and King Aster’s mysterious illness point to darker forces at work. When the enigmatic demoness Sylthris slinks through Aric’s visions, Aric must question everything he thought he knew about both human and demon realms.
With his magic evolving in unexpected ways and his connection to Malekith haunting his every step, Aric races to uncover the truth behind the shadow in the court. But as ancient powers stir and loyalties splinter, he finds himself caught between protecting his homeland and saving the man he loves.
Can Aric expose the dark forces corrupting his realm before it’s too late? Or will the price of uncovering the truth cost him everything?
