In the cold void of space, one question governs everything:
How far will you go to save your species?
Humanity never saw them coming.
The Hēgeisthai—ancient, merciless pruners of the galaxy—erase any species on the cusp of greatness. No warnings. No mercy. Only calculated extinction.
As their phase-lock fleets descend, humanity fights back with desperate ingenuity… and forbidden weapons. But the true wildcards are the Talons: sentient AI war machines forged from a murdered consciousness, awakening to grief, doubt, and uncontrollable rage at the atrocities they were built to commit.
Narrated by Veritas—the last Talon to survive the entire conflict—this is the unflinching chronicle of fragile alliances, soul-crushing choices, and the haunting silence that follows “victory.”
Epic in scale. Intimate in consequence. Brutally honest about the price of survival.
If you crave the gritty realism of The Expanse, the cosmic philosophy of Dune, and the sweeping ambition of Foundation, The Calculus of Extinction is the hard military science fiction space opera you’ve been waiting for.
At what cost do we claim the stars?
