Sue Burke's sweeping, award-finalist, SF Semiosis epic 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.
