Torrent of Darkness — Deirdre Gould

Out of fifty thousand, only thirty-three survived the Keseburg and the alien AI called Issk'ath. Hurtling toward an unfamiliar planet with few supplies and no preparation, they believe they are the last of humanity.

But Indra, trapped inside Issk'ath's colony, knows better. What she uncovers of the Keseburg's past forces her to confront the lies that governed her entire history. Her thirst for justice leads the colony down an ever darker path that risks them all.

Issk'ath must make a choice: Betray its directives to save them and face its own termination, or help Indra get the justice she is bent on and risk Earth, itself.
