When his mate is threatened, nothing burns hotter than his wrath. Against all odds, Arcanthus found Samantha, his beautiful, sweet terran mate. His fated one. Her love shattered the barriers around his heart. After defeating a ghost from his past, Arc thinks he and Samantha are safe to move on with their lives. But she has a past of her own, and it refuses to let her go. He nearly lost her once. He will not take that chance again. ——- Imporant Note: Vengeful Heart is not a standalone. This story features Arcanthus and takes place after Silent Lucidity and Shielded Heart, both of which should be read to enjoy this.
