Four billion years ago, in the Andromeda Nebula, an ancient alien race launched an ambitious project. Finding no other intelligent life in the universe, they tasked their massive supercomputers with seeding new races capable of developing sentience. This effort, called the Omega Program, ultimately produced humanity, though it also gave rise to other intelligent species. In the distant future, those creations confront humanity with the deadliest threat it has ever faced. As the various products of the Omega Program clash in violent opposition, Earth, outnumbered and outgunned by a technologically superior foe, relies on the program’s secret fail‑safe for its final hope.
