Entire worlds fall before a single Planetstrider Legions are burned to ash. Mechs are torn apart like toys. Their cannons are powerful enough to destroy dreadnaughts in orbit. Now the Vkash clan has brought three of those beasts to a remote, worthless world, and a disgraced warrior will do anything to find out why—and anything to stop them. T'kon of the Azi clan undertakes the impossible to right the injustice inflicted upon his people, and to restore his honor. If he succeeds, the ghosts of the fallen will finally rest. If not, he will die disgraced, and unmourned. Planetstrider is the prequel to the novel Behind the Lines, Book 1 of The Ganog Wars.

Mankind's newest fleet has just been obliterated. Attacked without warning, enemy unknown. Their last transmission originated from a world on the edge of known space. Alpha Company is dispatched to investigate. They’re the best of the best. Hardcore warriors piloting battle-tested mechs, they’ve never lost an engagement. Until they arrive on Ganog 7. Now, shattered and stuck behind enemy lines, the remnants of Alpha Company struggle to survive. Between them and escape stand three Planetstriders, thousand meter monstrosities capable of destroying an orbiting capital ship. In order to survive, they must disable these titanic war machines, an impossible task made even more difficult by the discovery of a terrible secret – one that must reach fleet command, no matter the cost.

Mankind drove back the Imperium at Ganog 7, but it was a pyrrhic victory. Their fleets are shattered, and it will take months to rebuild—time they do not have. Nolan and T’kon are sent to the Azi home world. Their orders—trick the Azi Clan into bringing the location of the Coalition shipyards to the Empress. When the Ganog fleets come, Fizgig and the Coalition fleets will be waiting in ambush. Yet neither the Coalition, nor the Empress are aware of the true threat. The Nameless Ones have returned, and their seekers are everywhere. They will stop at nothing to unseat the Empress, and seize control of the Imperium for their dark masters. Only the Tigris Khar, trapped on Imperalis, can save her. Caught in a web of duty and honor, the warrior must choose. If he saves his enemy, he damns himself, but if he refuses to help, then the entire galaxy will burn.

Imperalis has been lost. The Nameless Ones have returned. The Coalition refuses to fight, leaving the Ganog to wage a war they cannot win. Betrayed and cut off, Khar and Zakanna struggle to survive. Nolan and Burke bring Alpha Company to reinforce the Nyar home world, only to be overwhelmed by the mighty Void Wraith Omegas. Fizgig and Takkar are captured by the sadistic Kthul fleet leader, Azatok. Only one guttering flame of hope remains. On Nyar, Nolan finds an ancient Void Wraith Omega, weathered and damaged. If he can restore it, they might just have a weapon strong enough to fight back.
