Geodesica Series by Sean Williams, Shane Dix

The year is 2388. Humanity has spread to the stars, but the far-flung Arc Systems chafe under the tight control of the Exarchs, post-human AIs whose domination of Faster-Than Light technology gives them unsurpassed power. Then the discovery of a vast hyperspatial labyrinth known as the Geodesica changes everything.

Geodesica: Descent concludes the compelling, space-faring adventure begun by Geodesica: Ascent. Three unlikely allies begin plotting their revenge against an artificial intelligence behind the destruction of the system of Bedlam--and fight to control the ancient labyrinth of Geodesica.
