The Semiosis story continues in Interference as the colonists and a team from Earth confront a new and more implacable intelligence.

Over two hundred years after the first colonists landed on Pax, a new set of explorers arrives from Earth on what they claim is a temporary scientific mission. But the Earthlings misunderstand the nature of the Pax settlement and its real leader. Even as Stevland attempts to protect his human tools, a more insidious enemy than the Earthlings makes itself known.

Stevland is not the apex species on Pax.

Usurpation, the third book in the trilogy, is coming in May 2024.

Rainbow bamboo grows everywhere on Earth, and it wants to dominate — with compassion.
