System Zero Book 4: A Mobile Suit Military LitRPG Romance

By Karis Chan

This is how the war ends - not with a victory, but with a transmission.

Captain Vesper Krell holds the evidence that topples the people who started it all. The architects of the lie hold the orbital strike that will bury her first. Between them: a forty-minute window, an **eight-second deadline, ** and a buried protocol her aunt encoded eighteen years ago for one purpose - **to make a war machine say *no*.**

At **ninety-one percent sync, ** Auntie is no longer just a System. She's family. And when the math says everyone Vesper loves should die, Auntie does the one thing no machine is authorized to do.

The cities will stand. The guilty will fall. And on a quiet harbor where the fishing boats are finally coming home, two people who were born enemies will learn the hardest skill of all: how to *stay*.

**Series finale - mecha - steamy HEA. System Zero, Book 4.**
