Our take
A door to survival opens onto a conflict far larger than salvation.

This is big-idea science fiction with multiverse scale, political tension, and the momentum of a thriller.

"An immense achievement, an impeccably crafted book without a single word out of place." —The New York Times

Ideal for readers looking for epic science fiction about alien societies, human conflict, evolutionary inheritance, and morally difficult choices.
An Alien Light
Sci-Fi · First Contact
Our take
Called “an attractively complex portrayal of an alien species” by The Washington Post, An Alien Light follows two warring tribes brought together as subjects in an alien experiment that could determine humanity’s fate on Earth and across its galactic colonies, with a 4.1-star rating from more than 170 Amazon reviewers. Ideal for readers looking for epic science fiction about alien societies, human conflict, evolutionary inheritance, and morally difficult choices.
Choose your retailer
About the book
In this epic science fiction tale by an award-winning author, two warring tribes are the subjects of a strange alien experiment.
Epic in scope, peopled by characters from every strata of profoundly different societies, An Alien Light is an unflinching look at the strengths and weaknesses of the genetic, evolutionary, and historical inheritance that all of us share.
Arys, a glassblower and outcast.
Jehane, a skilled female warrior.
Dahar, with a deeply inquisitive mind.
Grax, an alien with profound doubts.
These four and hundreds of others are thrown together in an experiment to determine the fate of humanity, both on Earth and in her galactic colonies. For the Ged, the stakes are nothing less than the outcome of a war. For the humans, ignorant of the larger situation, the rewards for participating are incredible riches. But no one except the alien Ged understands the criteria for being chosen.
When that knowledge comes, there is no agreement about if, how, or when to use it. Some will betray others. Some will sacrifice. Some will die. And some must succeed, no matter the price.
Praise for An Alien Light
"This heady mix of fantasy and sf explores humanity's infinite capacity for change. Highly recommended." —Library Journal
"An attractively complex portrayal of an alien species." —The Washington Post
"Nancy Kress has the true storyteller's gift—the ability to make her characters and what happens to them so vital that the reader's heart aches." —Stephen R. Donaldson
