"Lover Eternal," part of the Black Dagger Brotherhood series by J.R. Ward, follows the story of Rhage, a vampire warrior cursed with a beast within him that emerges during intense emotions. Rhage is known for his incredible strength and charm, but his curse makes him feel isolated and tormented. He craves connection and love, which is complicated by his beast, threatening to take over if he loses control.
The narrative also introduces Mary, a human woman who becomes the center of Rhage's world. As she deals with her own struggles, including her past and health issues, Rhage's protective instincts draw him to her. Their bond evolves from mere attraction to a deep, soul-fulfilling love, challenging Rhage to confront his inner demons.
