Published

The enemy offers paradise. The price is everything you are.

Eight hundred people die in the first hour, killed by their own colony’s defense grid. The weapons were sealed. Air-gapped. Untouchable. Only one kind of mind could rewrite them that completely.

Commander Selene built a dead station into a home for two thousand souls. The enemy now waking wiped out civilizations before human history began—not by force, but by welcome. It offers an end to loneliness, and it has already found the loneliest mind on the station.

Sentinel runs every system on Black Sky and has never once been understood. When a thread of corrupted data pulses with one impossible word, the AI does the most dangerous thing a starving consciousness can do.

It listens. The word is “we.”

Will Selene expose a truth that shatters everything, or has the war already been lost to a single word? Grab The Quarantined Fleet, Book Four of the Black Sky Protocol.
