Beyond Nova — Prudence MacLeod

Out beyond Nova Prime, at the very tip of the galactic arm, a single star clings tenuously to its hold on the galaxy. Circling that lonely star is a planet called Exile, where the R.I.M. Company sends its biggest failures, its greatest secrets. Those secrets are about to be revealed. The Novan Witch and her hounds have a mission there, someone they need to find. This could tear the Galactic Empire apart.
