Night is falling. The unstoppable Hegemony invasion has reached the very heart of the Confederation. Battle after desperate battle has been fought, and each time, the Confeds have been pushed back, columns of battered and blasted ship retreating from system to system. Now, they prepare to grimly defend the capital world of Megara, the very center of the Confederation. Tyler Barron prepares for what could be his final battle, a final desperate defense, one last chance to stem the tide of Hegemony conquest and subjugation.

The Hegemony has launched the invasion Tyler Barron and his Confederation comrades have feared, and all the Rim is ablaze with the fires of war and destruction. The Hegemony has brought its vast fleets, its advanced technology, and its endless legions of grim cyborg warriors to impose its system of rigid genetic hierarchy over all humanity on the Rim. The Confederation fleet is outnumbered and outmatched, but they will fight nevertheless, struggling and dying to hold back the onslaught any way they can.

The Confederation and its allies have won their first victory, retaking their capital from the forces of the Hegemony. But the enemy is not beaten, far from it, and they are back, with an unstoppable weapon, a vast superbattleship, a deadly hybrid of imperial and Hegemony technology, called the Colossus. The great ship is enormously powerful, nearly unstoppable, and in its armored depths it hides a secret, another Hegemony weapon, one that will change the dynamic of the entire war.

Admiral Tyler Barron and the Confederation navy face a new threat, darker and deadlier than any that have come before. The Confederation has just concluded its war with the Hegemony, but now that power, so long the hated enemy, is calling for help, for the Confederation to join it to face a deadly invasion, one likely to subjugate all humanity. Barron must overcome his own resentments, and the resistance of the Senate, and find a way to lead his forces into battle once more. The odds are long, but the stakes couldn’t be higher, no less than a choice between survival and freedom.

The mysterious enemy has come, and Tyler Barron and his allies prepare for the final battle, the desperate struggle to save the Rim. Barron’s spacers are ready to fight, as always, but this time they know little of the enemy, and they face technology far beyond their own. They will fight to the end if necessary, battle with their final breaths to hold back the deadly enemy. They will stand alongside their old enemies, the Hegemony, united for one massive battle, one all out effort to stop the Highborn.

Tyler Barron is about to lead his fleet into a trap. He is sure the enemy is laying in wait, but he has no choice. After four years of unexpected calm along the front line, the Senate and the Hegemonic Council are demanding action, and the Pact’s commanding admiral has no choice but to set out on a mission to liberate the enemy-held regions of the Hegemony. While Tyler prepares for an offensive he believes can only end in disaster, Andi Lafarge is preparing to continue her quest for the mysterious weapon the doomed empire used to defeat the Highborn centuries before. 

The war is over, but the struggle continues. Tyler Barron and his spacers have set out into the unknown, deep into the Badlands, seeking to discover the empire’s old tech and the secrets of its tortured history before Gaston Villieneuve and the resurgent Union can beat them to it. The White Fleet is a vast force, powerful, and crewed by the toughest veterans from the war. Barron and his people know the future of the Confederation, even its survival, depends on recovering the scientific secrets of the empire before the enemy can do the same.

A battle is coming, the greatest the Rim has seen in 10,000, a fight for freedom, for the future, for the very survival of all humanity holds dear. Tyler Barron and his comrades are ready for their greatest test, but even as they prepare to hold the line at Fortress Striker, to turn back the Highborn’s imminent attack, the enemy have opened another front, one far to the rear. 

Captain Tyler Barron and the crew of Dauntless are finally enjoying the rest they've earned while their aging battleship gets the repairs and refit it desperately needs. But their respite will be short-lived. In the Badlands, deep in the haunted vastness of pre-Cataclysmic space, a new discovery threatens to upset the balance of power. Orbiting a world in a distant system is an ancient battleship, vastly larger and enormously more advanced than anything possessed by the contending powers.

The pulsar...an ancient weapon of unimaginable power, one that threatens the Confederation with total destruction. The Union is preparing for the final invasion, one that cannot fail with the great artifact at the head of their fleet. The clock is ticking quickly toward midnight. There is a chance to avoid annihilation, a small one. The Confederation has its own ancient device recovered from the Badlands, a stealth generator. It is not as powerful as the pulsar, but it just may be enough.
