On a small corner of a doomed world, where the capricious laws of nature can’t be reversed, a civilization arrives at the end of its days.
Warin is one of a small team charting the demise of the last few inhabitants of Retti 4, a distant planet in the throes of an extinction-level virus. It’s not Warin’s job to intervene in natural volution or to question the whims of a cruel universe. He is only to observe and report. Until Warin actually steps foot on Retti 4.

Not the primitive species Warin believed them to be, the rettys are an industrious and ethical lot working together in a close-knit farming village. Lacking the human traits of fear, suspicion, and aggression, they are welcoming, curious, and eager to share their traditions—even in the shadow of a tragedy that they, and Warin, are powerless to stop.

As they embrace Warin into their fold, his compassion grows. So does his own self-discovery. For Warin, far away from Earth, comes a deeper understanding of friendship, civilization, and the true meaning of humanity. And above all, the peace and profound strength it takes to accept the inevitable.
