Eden

Phoa was terraformed by nanite swarms for Earth's colonists to create a beautiful, habitable world. But the swarms evolved, overran the planet, and two centuries later, threaten every living thing remaining on it. Reyes, a scientist from Phoa's last colonial enclave, and Thanata, a bioengineered hunter from a rival tribe, must work together to halt the Green: the massive swarm that absorbs plants, animals - even entire cities. But if the unlikely pair hopes to survive the mutated wilds and the deadly Green, they'll have to learn to understand each other.

Though the Green has been temporarily pushed back, Reyes and Thanata face a new challenge in a deadly strain of coral biota that has spread over the region. It taints the planet’s rainfall, rivers, lakes - and all the wildlife that depends on them. But there is a swarm-like signal inherent in the coral, which originates deep within Phoa’s biomorphic sea. Reyes and Thanata must rush to its source and stop the coral growth before it suffocates everything they have struggled to preserve - including the bond between them.

With Phoa stabilized against the Green and Tiamat’s coral, Reyes and Thanata have inspired people to work together against the swarms. Yet while exploring an old colony ship, they discover a message warning them of catastrophe. The voice belongs to Reyes’ estranged father, who warns that a final protocol left by the first colonists will doom Phoa. Soon, meteors land in every settled region and transform into swarms that devour everything around them - all while a huge, ringed structure hovers in the sky.
