Age of the Empress

Introduction (blurb)
From Simon and Schuster.com

Star Trek: Enterprise® She seized power in a heartbeat, daring to place herself against all the overlords of the Empire. Empress Hoshi Sato knows the future that could be; now all she has to do is make sure it never happens. For her to rule, she must hold sway not only over the starship from the future but also over her warlords, the resistance, and her Andorian husband. As quickly and brutally as Hoshi seized power, imperial rule is taken from her. Her only chance to rule again is to ally herself with a lifelong foe, and an alien.

“You’re speaking with Empress Sato. Prepare to receive instructions...”

Her name inspired fear in the hearts of her enemies, and adoration among the billions of sentient beings who knew her as their absolute ruler – Hoshi Sato. The tale of Sato’s rise to power is well-known, but the story of how she defeated the alien Rebellion and united the Terran Empire has never been told in full. Until now... The Empire is at war with itself. The discovery of the Starship Defiant has given the enemy pause, but the new Empress needs an experienced military commander to take the fight to the rebels and eliminate them once and for all. To that end, she will unite her forces -- and her fate -- with the one man who can save the Empire from itself: her new consort, General Shran of the Andorian Imperial Guard.

Restoration reveals the rise of Empress Sato. Ruthless with the power of a starship from the future, Sato looks to cement hercontrol over the Terran Empire by forcing the Andorians underher control and taking General Shran to be her consort…whilesimultaneously using the Terran and Andorian forces to crush the Vulcan rebellion. The Sorrows of the Empire shows Spock taking control of the Terran Empire and putting a plan into motion that will bring the Empire to an end. But it seems Spock miscalculated as a harsher force emerges to take over and enslave all humans.
