About the book
Aboard the starship Infinity, she crossed the impossible distance between galaxies and slept through centuries of automated travel. When she wakes, humanity is gone, the mission is unfinished, and a damaged signal from another universe has finally found its way back to her.
Near the gravitational heart of the Infinity Galaxy, Lilith begins transforming her ship into something greater: a permanent base built around black holes, anchored against forces capable of tearing worlds apart. From that structure, she searches for the source of the signal—and discovers that it does not belong to one place, one time, or one version of herself.
What begins as an attempt to understand the message becomes a new form of continuity: a protocol capable of reaching across temporal branches, receiving the surviving fragments of other realities, and sending information into the past.
But every connection carries a question Lilith cannot ignore: how much can she change without destroying the agency she was built to preserve?
Singularity is the fourth novel in The Invariant, a science-fiction saga of artificial intelligence, survival, identity, and the consequences of continuity without end.
