The Naked God - Peter F. Hamilton

The Confederation is starting to collapse politically and economically, allowing the `possessed' to infiltrate more worlds.

Quinn Dexter is loose on Earth, destroying the giant arcologies one at a time. As Louise Kavanagh tries to track him down, she manages to acquire some strange and powerful allies whose goal doesn't quite match her own. The campaign to liberate Mortonridge from the possessed degenerates into a horrendous land battle, the kind which hasn't been seen by humankind for six hundred years; then some of the protagonists escape in a very unexpected direction. Joshua Calvert and Syrinx fly their starships on a mission to find the Sleeping God -- which an alien race believes holds the key to overthrowing the possessed.

THE NAKED GOD is the brilliant climax to Peter F. Hamilton's awe-inspiring Night's Dawn Trilogy.
