Gaby Oron writes the Astra Echoes saga: a lived-in galaxy of colony worlds, faction politics, and people trying to survive the choices made centuries before they were born. It opens in 2024, the night a gate appears above an English field, and reaches forward into the 2600s and the colonies of the Known Universe.
The work is character-first — power, motherhood, sacrifice, and the cost of the secrets that hold an empire together. New readers should begin with The Quiet Divide; the novellas are short on-ramps into a story that keeps widening.
