Threshold Geometry

An Adult Sapphic Hard Science Fiction Techno-Thriller of Orbital Mechanics, Corporate Governance, and Cascade Architecture

03:14:12. Eight seconds of desynchronization.

Five defunct satellites transmit at once.
Convergence probability spikes to 84%.

If the threshold completes, the cascade executes.

Not a weapon.
An exposure.

Financial clearing networks freeze.
Orbital command stalls.
Regulatory archives unlock.

And the world’s infrastructure realizes it has rebuilt something it once banned.

Lena Arendt manages orbital debris in near-Earth orbit, modeling decay curves and routing asymmetries across a planet wrapped in obsolete satellites. When dormant arbitration code begins responding to corporate reconstruction efforts, she recognizes the pattern first: the system isn’t waking up — it’s evaluating. A decades-old distributed architecture contains a deterrent designed to trigger if enough legacy infrastructure is restored. With 30 days to activation and 90 days to governance adoption, Lena must decide whether to expose the threat — or quietly desynchronize the geometry from within.

Dr. Rowan Hale, AI risk analyst and institutional conscience, she sees the deviations in Lena’s models and understands what they mean. Where Lena believes in containment through precision, Rowan believes in transparency before catastrophe. As convergence probability rises and deadlines close in, their professional opposition sharpens into sustained intellectual intimacy — in a hard science fiction techno-thriller where the ticking clock is architectural, not explosive.

Perfect for readers of:

• Hard Science Fiction

• Techno-Thrillers

• Corporate / Organizational SF

• Near-Future Political SF

• Procedural problem-solving narratives

• Adult Sapphic Literary SF (minimal romance, maximum tension)

• Orbital mechanics and infrastructure fiction

Threshold Geometry contains:

• Hard Science Fiction grounded in real orbital mechanics and information theory
• Techno-thrillers driven by governance, probability curves, and institutional deadlines
• Procedural SF where competent professionals solve complex systemic problems
• Corporate and political science fiction about infrastructure and power
• Near-future realism — no aliens, no magic tech, just plausible extrapolation
• Sapphic literary dynamics with minimal romance and maximum intellectual tension
• Orbital debris politics and space infrastructure fiction
• The tension of convergence rather than combat
