A novel series by Marcus Pessoa
Hard science fiction about the boundaries that define us.
Borders of Existence — Book One
The Boundary Within
- Hard Science Fiction
- Consciousness
- grief
One hundred and fifty years after nuclear war reduced humanity to a single island and an orbital station, two interstellar arks are being built to carry the survivors to a distant star. The ships are ready. The cryogenics work. The cloning systems can rebuild a population from genetic archives. The AI that must pilot them through a hundred thousand years of unknowable space does not exist yet.
In a world where political conspiracy, religious opposition, and personal vendetta converge on the technology that could save or destroy the species, the boundary between human and machine consciousness isn't the line everyone is fighting over. It's the limit within each of us. The place where fear decides what we're willing to see.
The Boundary Within is the first novel in "Borders of Existence," a hard science fiction series exploring what it means to be human when the answer is no longer obvious.
“I spent more than three decades operating, designing and managing complex systems. The questions those systems couldn’t answer are the ones this fiction tries to ask..”
Marcus Pessoa is a researcher, university docent, and former Brazilian Air Force pilot and systems engineer.
