Citadel

The second entry in the bestselling Troy Rising saga and follow-up to Live Free or Die from multiple New York Times and USA Today bestseller John Ringo! When the orbital gates first materialized in the outer solar system, all seemed well. And, lo, peaceful traders made first contact so whatever came next couldn't be so bad, could it? Yeah, it could. Very bad. Now humans have battled back from a Trojan-horse-like conquest by a tyrannical alien species to become a force to be reckoned with in the galaxy. On a crash-building course, we've built a near-impregnable battlestation of Deathstar proportions to prove it. But the enemy is remorseless and to survive we must take the fight to our attackers and prevail! Unfortunately, the bones and burnt hulks of those who have tried litter the star-ways. But these galactic imperialists have never contended with humans, a foe who is their match in sheer ferocity and desire to win.
