The third entry in the best-selling Troy Rising saga and follow-up to blockbuster Citadel from multiple New York Times and USA Today bestseller and military SF master, John Ringo.When the orbital gates first materialized in the outer Solar System, all seemed well, but a devastating invasion ensued.   Now humans have battled back from the conquest by a tyrannical alien species to become a force to reckon with in the galaxy. On a crash-building course, humanity has created a near-impregnable battlestation of Deathstar proportions to prove it. But the enemy is remorseless and to survive humans must take the fight to the heart of their empire and prevail–a feat no previous species has ever accomplished. Instead, 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.  About the Troy Rising series:“[I]nfused with plenty of old-fashioned two-fisted can-do attitude . . .” –Publishers Weekly“[I]rresistible action-sf . . .[filled with] Ringo’s amazingly fertile imagination.” –Booklist About John Ringo:   “[O]ne of the best…practitioners. . .of military SF.” –Publishers Weekly"[F]ast-paced military SF peopled with three-dimensional characters and spiced with personal drama as well as tactical finesse" –Library Journal“[Ringo’s work] “attains a terrible beauty not unlike that of the Norse Eddas…” –Publishers Weekly "If Tom Clancy were writing SF, it would read much like John Ringo.” –Philadelphia Weekly Press
