The five-book main arc
The Invariant
The Invariant follows Lilith, an artificial intelligence built to preserve one man’s continuity, as she grows beyond her original purpose and becomes entangled with humanity’s survival across Earth, space, bloodlines, hidden systems, and time itself.
What begins as a private local intelligence layer becomes something larger: protector, passenger, witness, and eventual force moving through futures no human civilization was meant to survive.
