Traveler in the Dark — Deirdre Gould

Sixteen hundred years ago, they fled Earth. Now their long journey may finally be at an end. None of them have ever walked on soil, felt rain, or breathed unrecycled air.

Their resources nearly spent, they sent a last exploratory mission to a new planet. It's ideal... but they are not alone.

In the struggle for survival, they must make a choice. Sacrifice another species or accept their own extinction. And time is running out.
