A Percabeth AU: An Unfamiliar Design

In the city that never sleeps, Percy Jackson and Annabeth Chase have finally found peace.

Years have passed since the tumultuous reunion in San Francisco. Now settled in the heart of New York City, the two have built the "perfect" adult life. Annabeth is a rising star in the architectural world, currently spearheading the construction of the ambitious Vanguard Tower. Percy has carved out a prestigious career as a marine biologist, trading high-school brawls for the quiet complexity of the Atlantic's ecosystems.

But stability is a fragile thing.

When a mysterious tremor shakes their apartment and Annabeth's master blueprints begin to "bleed" a dark, corrosive ink, their world is thrown into a tailspin. It isn't magic-it's something far more calculated. A series of high-tech sabotages and cryptic messages suggest that a shadow from their past has returned, one who doesn't need a sword to dismantle their lives.

As the "Vanguard" project begins to crumble under the weight of an impossible structural failure, Percy and Annabeth must use their wits, their professional expertise, and their unshakable bond to uncover a conspiracy that threatens to destroy everything they've built.
