Jace, a defective Omega in Mirror City's ABO hierarchy, accidentally triggers a fatal four-way band-lock with three Apex Alphas—Caleb, Darius, and Vance. Without high-dimensional resonance, he will die within days. Trapped in their Alpha-only dorm, he resists pheromone pressure and refuses to become anyone's plaything, while the three Alphas fall into jealous rivalry over him. Jace survives schemes by Omega Stella and corrupt officials Silas and Gideon, then learns he is secretly the hybrid heir of Genesis Pack Alpha and an S-Class Beta Arbitrator, his supreme power sealed by micro-inhibitors. Vance carries the deadly Spectral-Tear virus, curable only by Jace's stem cells. After near-death betrayals, Jace awakens his power, defeats Silas, and becomes Mirror City's supreme Apex. Vance is revived, and they achieve perfect golden-band integration, leaving Caleb and Darius with unrequited feelings.
