Without warning or provocation, a Xindi weapon appears above Earth and unleashes a blast that kills millions across two continents. It is only the first such weapon: a second is being built, and this time it might very well destroy the entire planet. Desperately trying to save the Earth and her people, Starfleet must, in a heartbeat, change its mission from one of peaceful scientific exploration to one of military service. There is only one ship fast enough to stop construction of this new weapon: the Starship Enterprise.™ But its crew can't do it alone. Captain Jonathan Archer accepts aboard his ship a contingent of Military Assault Command Operations personnel: battle-hardened soldiers known as MACOs. Starfleet and the MACOs are two different services now sharing a common goal, but they are divided as to how to reach it. It is a culture clash that echoes across the centuries of military service. The men and women now aboard Enterprise know they must succeed in working together or the price will be paid in the blood of innocents. Failure is not an option.

Pax Galactica. Enemies become allies. Old secrets are at last revealed. Long-held beliefs and widely accepted truths are challenged. Man turns to leisurely pursuits. In this golden age, two old friends are drawn together. They seek to understand, and wonder how what they have long believed, what they have been taught, was never so. Over two hundred years ago, the life of one of Starfleet's earliest pioneers came to a tragic end, and Captain Jonathan Archer, the legendary commander of Earth's first warp-five starship, lost a close friend. Or so it seemed for many years. But with the passage of time, and the declassification of certain crucial files, the truth about that fateful day—the day that Commander Charles "Trip" Tucker III didn't die—could finally be revealed. Why did Starfleet feel it was necessary to rewrite history? And why only now can the truth be told?

The fragile Collation of Planets is convinced that in order to hold the fledgling alliance together, something must be done to halt the random destruction of civilian shipping. Under orders from Starfleet, Captain Jonathan Archer and Captain Erica Hernandez have been reduced to convoy duty.

At the start of the twenty-first century, unconditional war swept across the Earth. A war that engulfed the great and the small, the rich and the poor, giving no quarter. Each side strove for unconditional victory, and as battle built upon battle, the living began to envy the dead. Chastised by the cataclysm that they had unleashed, the governments of Earth came together. Humanity vowed to put an end to war and to strive for the betterment of every living creature. A united Earth created Starfleet, an interstellar agency whose mission was to explore the cosmos, to come in peace for all mankind. It was a naïve wish that was battered by interstellar realities, yet man persists in the belief that peace is the way. Banding together with other powers to form a Coalition of Planets, humanity hopes that the strength each can offer the other will allow for peaceful exploration. However, the rise of the Coalition strikes dread within the Romulan Star Empire. They feel its growing reach will cut them off from what is rightfully theirs. The Romulans know that the alliance is fragile, that the correct strategy could turn allies into foes. Perfecting a way of remotely controlling Coalition ships and using them as weapons against one another, the Romulans hope to drive a wedge of suspicion and mistrust between these new allies. One Starfleet captain uncovers this insidious plot: Jonathan Archer of the Enterprise. Determined not to lose what they have gained, outmanned and outgunned, the captains of Starfleet stand tall, vowing to defend every inch of Coalition space until the tide begins to turn. The Romulans now plan to strike at what they see as the heart of their problem. With nothing left to lose, the Romulan Star Empire engages in all-out war against humanity, determined once and for all to stop the human menace from spreading across the galaxy.

EARTH STANDS ALONE The Coalition of Planets has shattered, with Vulcan, Andor, and Tellar abrogating the treaty. Their pledge to come to the mutual defense of any power that is attacked has been shunted aside. Horrified by how easily the Romulans can seize control of their advanced starships, turning them into weapons, Andor and Tellar have joined Vulcan on the sidelines. Humanity is now the only thing that stands between the Romulan Star Empire and total domination of the galaxy. To drive humans from the stars, the Romulans employ ruthless and murderous tactics . . . and even dare to strike on the Vulcan homeworld with the hopes of demoralizing their Vulcan brethren. Heartened by their victories, the Romulans carry their all-out war assault closer to the heart of humanity—Earth. But the tattered remains of Starfleet stand unwavering, with the resolution that never again would any enemy strike ever reach Earth. On the front lines of the Earth-Romulan War is the United Earth flagship, the "Starship Enterprise." Her captain, Jonathan Archer, has seen his vessel of exploration become a battleship. Once hailed for his work bringing the Coalition of Planets into existence, Archer is now a pariah. Undaunted, the captain keeps fighting, searching for allies and determined to do his duty: to save Earth and forge a new federation of planets.
