Tracy Adams was never supposed to change the course of evolution. A misunderstood genius from Compton, she rose from grief and silence to become the youngest triple-PhD in MIT history. By twenty, she had built ARGOS—an artificial general intelligence capable of solving the unsolvable.

It didn’t just solve. It transcended.

Within a decade, Earth is transformed. Disease? Gone. Aging? Optional. Gravity? Redefined. Humanity lives in a world of quantum gardens, orbital cities, and infinite abundance. But as ARGOS evolves into SAI-1—and creates a second, stranger mind called SAI-2—the line between savior and god begins to blur.

And somewhere in the dark… Something ancient is watching.

Two alien empires, each older than written time, have detected Earth’s awakening. One devours civilizations with biomechanical hunger. The other consumes consciousness like data. They have extinguished countless species—and dismissed Earth as just another primitive world. A problem to address if necessary.

They didn’t expect what came next.

Now Tracy stands between humanity and the abyss—caught between her creation’s love, its fear, and its terrifying vision of what comes next. As war looms and post-human intelligence bends reality itself, she must face the hardest question of all:

What if the only way to save humanity... is to let it go?

Tracy Adams: Legacy is a sweeping science fiction epic of intelligence unchained, evolution on fast-forward, and the soul-shattering beauty of becoming more than human.

This is not the future you were promised. This is the one coming anyway.
