For three hundred years, humanity has crossed the stars along corridors its navigators trust like solid ground. Commander Renata Oyelaran has signed hundreds of those charts, staking her name—and countless lives—on roads everyone believes are permanent.Then a single survey reveals an impossible error.At first it's only a star, shifted by a fraction no one else can see. But as more anomalies appear, ships vanish, colonies become isolated, and trusted routes begin to fail. The deeper Oyelaran digs, the more she realizes the foundations of interstellar civilization are built on something humanity has never understood.Her investigation follows the trail of a mentor who disappeared years earlier after uncovering the same impossible truth. Now, as rival powers race toward war over the last reliable routes, Oyelaran must solve a mystery older than human civilization itself before the galaxy fractures into thousands of unreachable worlds.Some maps aren't discovered.They're built.
