Timeweb by Brian Herbert

Brian Herbert creates a universe of wondrous possibilities that is populated by sentient spaceships, shapwshifters, intriguing robots, and miniature aliens with mysterious powers. Humanity has become a mercantile society that has spread throughout the galaxy, ruled by wealthy merchant princes who live in decadent splendor—entirely unaware of another realm just beneath the fabric of the universe.

When galactic ecologist Noah Watanabe discovers the cause of a strange, cosmic disintegration, he embarks on an epic journey to restore the ancient balance to the crumbling galaxy. Noah must work with warring, alien races to unlock the secrets to a vast celestial puzzle.
