The Shadow of Olympus: The Twin Primordials

​Percy and Nico have faced down forces of cosmic unmaking and discord, but their greatest challenge awaits. A primordial of pure, unblemished order has awakened, and it sees the two heroes as a fundamental flaw in the perfect, pristine design of the universe. To this being, their love, their souls, and their very existence are a paradox that must be corrected.
​Faced with a series of harrowing trials-tests of their love, their past, and their souls-Percy and Nico must prove that they are not a mistake, but a new, necessary law. But as they win the battle against the primordial of order, they attract the attention of even older, more terrifying powers.
​When they are summoned to the legendary Council of Creation, they must confront the cold, hard truth: their victory has marked them for judgment. They are an anomaly in a universe of ancient beings, and their next fight is not for their lives, but for their right to exist.
