The crew of the Artemis has escaped the nightmare of Paradise-1, but at great cost.
Parker is gone. Petrova’s past continues to haunt her. Worst of all, Erebus — a timeless entity of pure darkness — has been released from its prison.
Now it’s headed for Earth.
Petrova must rally her crew for one final mission. Somehow, they must find a way to unite the disparate factions of the solar system — the United Earth Government, the Lunar colonies, and the outer planets — and find a way to stop Erebus.
The fate of humanity — and the galaxy — is in their hands.
