Interference

"Narrators Caitlin Davies and Daniel Thomas May reprise their roles, and between them, they've once more captured the essence behind the voices of multiple characters, and even more impressively, this time there are non-humans thrown into the mix." — Bibliosanctum
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.
