When Ariella Quell awakens after six centuries in cryostasis on the alien world of New Nova, her memories are fragments—a fortune teller's prophecy, a nightclub called Le Glow, and green eyes like shattered starlight. The devastating truth: she and Prince Costa have been awakened and memory-wiped three times over 600 years, their love deemed too dangerous to exist. Ariella believes she's human until her abilities awaken, revealing the truth—she's a hybrid, daughter of the long-lost Princess Celeste of Solmere. Her very existence threatens the rigid separation between humans and Novans that keeps the ruling Council in power. When Costa awakens, their incomplete soul bond—interrupted during an ancient binding ritual—begins reasserting itself. As they flee through Voidhaven's impossible architecture to complete what was begun centuries ago, they discover their love story was never just about them. They were meant to be living proof that the two species could evolve together. But Lord Vexan and the Inner Circle will stop at nothing to maintain the separation that preserves their power. As Ariella's royal heritage is revealed and her hybrid abilities fully manifest, she and Costa must complete their binding ritual in the mystical Nexus—the same place where they were torn apart. Their love has survived 600 years of imprisonment, three memory wipes, and the collapse of civilizations. Now, as ancient networks reawaken across New Nova, their completed bond threatens to change not just their world, but the very nature of what it means to be human—or alien. A sweeping alien romance about love that transcends time, species, and the forces determined to keep them apart. Perfect for fans of alien romance, fated mates, and epic love stories that span centuries.
