A character-driven science-fiction saga by Gaby Oron — space opera across roughly six centuries of interstellar colonisation, faction war, and human survival. If you only do one thing, begin with The Quiet Divide.
The path through
Read them in order if you can — the books talk to each other, and threads planted in the novellas pay off later. The two openers are the best way in; the Echoes trilogy picks up four years after Ashfall Rising. Descriptions below are deliberately spoiler-light.
Dr. Cira Langley survives a catastrophic deorum experiment and discovers she carries something impossible. As Praetorium closes in, she and her husband must choose: trust the system or run before everything fractures.
When an impossible message reaches Somnia Magna from a world silent for generations, Captain Vivian Hayes is sent to find its source. What waits on Sacramentum is more than a distress call—and someone already knows she is coming.
Eight years after Meridian, Erigo is the oldest city on Sacramentum — until the reactor at its heart is pushed past the point of failure and six hundred thousand people are sealed inside their towers to die. Poppy Hadley digs out of the ash carrying her sister’s scorched locket and a message hidden inside it she was never meant to read. Mason Wright climbs out of the same rubble with proof the lockdown order was written before the reactor failed.
Good to know
Start with The Quiet Divide. It opens the series and introduces the Known Universe, the colony worlds, and the events the later books build on.
Astra Echoes is character-driven science fiction — space opera with colony worlds, faction politics, and survival, set across roughly six centuries.
Reading in series order is recommended, since later books pay off threads set up earlier. Start with The Quiet Divide (2597), then Ashfall Rising (2602). The trilogy begins four years later with Echoes of Erigo (2606).
The saga is told across novellas and full-length novels, beginning with two published novellas and continuing into the Echoes novels.
If you enjoy interstellar colonisation, faction politics, and survival under pressure across a lived-in galaxy, Astra Echoes is written for you.
