Exodus of Evil, Exodus of Evil (01) by James Flynn

The generation ship, Conservation, has spent the last twenty-nine years sailing through deep space on an interstellar mission.

With a crew consisting of humans, animals, insects, trees, and plants, the starship is a microcosm of planet Earth’s ecosystem and biomass. Conservation’s ultimate destination is Proxima b, an unpolluted, potentially habitable exoplanet where Earth’s travelling lifeforms can start a fresh, utopian existence.

The Universal Mining Agency, the corporation behind the Conservation Project, has been monitoring the ship’s progress ever since its launch, but when communication is suddenly cut off, panic and concern begin to rise.

David Kingston, a respected zoologist who donated a large amount of animals to the project, senses there may be something evil onboard the starship, and takes it upon himself to investigate.
