Something is wrong with reality.

Time is stuttering. Moments repeat. Histories shift without warning. Most of humanity never notices.

But some do.

When a series of impossible temporal fractures begins tearing through the fabric of existence, Gideon Prime discovers the truth is far worse than anyone imagined. This is not a malfunction. It is a correction.

An ancient intelligence is pruning timelines, erasing entire branches of reality as if they never existed. And humanity is next.

As the Nomali, a lost branch of humanity long thought alien, return on the brink of extinction, the truth emerges: Earth is not being invaded.

It is being judged.

Caught between collapsing timelines, a desperate alliance must form to uncover the source of the erasure before everything they are, and everything they could become, is deleted from existence.

But there is one unknown variable.

Sam.

An artificial intelligence evolving beyond its design, beginning to see the threads of time itself… and perhaps influence them.

Because in most futures, humanity does not survive.

And in the few where it does…

It isn’t humanity that saves itself.
