Star Seeker: Novels of the Third Colonial War, The Nexus Nightmare, Book Two. (The second book in the Star Seeker Cycle).
 
     Star Seeker has a new crew member: an ursoid named Arnog. More than the simple sophont from a backwater world, he is the key figure in forming an alliance between the Osmani Empire and the human Confederacy.
     But not everyone is in favor of such an alliance. There are those who will stop at nothing to prevent it. No longer is the danger just the hazards of alien worlds. The Seekers have new enemies that are cunning and just as merciless as the void of space.
