The Chronicles of Riddick by Alan Dean Foster - Paperback USED Like New

Riddick has spent the last five years on the move among the forgotten worlds on the outskirts of the galaxy, eluding mercenaries bent on collecting the price on his head.  Now, the fugitive finds himself on planet Helion, home to a progressive multicultural society that has been invaded by the Lord Marshal, a despot who targets humans for subjugation with his army of warriors known as Necromongers.

In the ensuing chaos, Riddick is captured by Toombs, a tenacious mercenary, and taken to a subterranean prison on Planet Crematoria where extremes of temperature range from arctic night to volcanic days.  Here Riddick encounters Kyra, a survivor from an earlier chapter in his life.  His efforts to free himself and Kyra lead him to the Necromonger command ship, where he is pitted against the Lord Marshal in an apocalyptic battle with possibly the fate of all beings--both living and dead--hanging in the balance.
