THE SONG OF DARKNESS. The Lost Tales of Erandelle, #1

The Song of Darkness Vol. 1 is a fantasy novel set in the town of Westbrook, a place where a hidden magical community-specifically an immortal race known as the Esir-has lived in exile for sixty years. After the death of their Aunt Abby, sisters Cassie and Megan Cooper return to their family's estate. Cassie, who possesses latent magical abilities she has tried to bury, finds herself inevitably pulled back into the magical world she once visited as a child.
But the town is not as peaceful as it seems. Tensions simmer between the magical residents and the Darkspear family (House of Kor'Shal), who rule with cold precision and seek the legendary "Book of Origins."Upon their arrival in Westbrook, Cassie becomes the focal point of a complex conflict between two Esir brothers, Gaelin and Daerion Darkspear. Gaelin, the fallen prince with a long-standing, complicated romantic connection to Cassie, struggles against his family's oppressive control.
While Daerion, the powerful warrior, discovers he shares a Doth'Ara-a rare, unbreakable soul bond-with Cassie, an event that upends his loyalties to his father and his brother. This narrative tracks Cassie's journey as she discovers her own mysterious, dangerous magical heritage, which makes her a target for the powerful patriarch of the Darkspear family, Cyran.
