The Hellhole Trilogy

Devastated by an asteroid impact, the planet of Hellhole is inhabited by only the hardiest and most desperate colonists. It is one of 54 remote frontier worlds forced to pay tribute to the corrupt Constellation, which is ruled by decadent nobles. In this epic story of clashing galactic empires from bestselling authors Brian Herbert and Kevin J. Anderson, the struggle for independence is about to be threatened by an even bigger obstacle than the powerful Constellation: deep beneath the surface of Hellhole lies the remnants of an obliterated alien civilization that, when unearthed, might just tear the whole galaxy apart.
