Transformation

The latest book in SF Grandmaster James Gunn's sweeping, space opera trilogy of the Transcendental Machine

Planets at the edge of the Federation have been falling mysteriously silent. The arrogant and recalcitrant bureaucracy running the Federation grudgingly allows two transcended humans, Riley and Asha, to investigate. They join forces with the Earth's Pedia, a global A.I., along with Tordor, a Dorian representative of the Federation, and Adithya, a member of a splinter group vowing to destroy the Pedia. No one on the team trusts one another.

They must find a common ground and the answer to the planetary silences in order to confront an enemy more ancient than the Transcendentals and more powerful than any Pedia.
