Mission: Eradicate. Obsidiar Fleet, #6

Mission: Eradicate. Kill or be killed. The discovery of the Vraxar planetship - Aranol - has revealed to the Confederation how much they are outgunned by the invading aliens. The Space Corps' successes to date will count for nothing if the largest spaceship in the known universe is allowed to reach human territory. Fleet Admiral John Duggan is not a man to sit on his hands while there is a chance to act.
He sends Captain Charlie Blake on a daring mission deep into Estral Space, to launch a pre-emptive strike against the Aranol and also to rescue the lost battleship Ulterior-2. Blake and his crew aren't alone - Lieutenant Eric McKinney and his squad are along for the ride and they're itching to get involved. What Blake finds is a long-forgotten war, still raging with incredible intensity. Surrounded by enemies, it will take every ounce of his ingenuity to achieve victory.
Where ingenuity fails, there are other, more direct options. His spaceship, the ES Cataclysm, is equipped with experimental and potentially devastating weaponry, as the Vraxar will soon discover. The Aranol has existed for millennia and overseen the fall of a thousand empires. It will not go down without a fight. Mission: Eradicate is a high-action science fiction adventure, which concludes the Obsidiar Fleet series.
