Star Trek: Vanguard #1: Harbinger: Harbinger - Harbinger

In the aftermath of Harbinger, Commodore Diego Reyes commands Vanguard while waging an intensely personal struggle, tasked to uncover the true significance of the Taurus Reach while simultaneously concealing that mission from his fellow officers -- and even his closest friends. As the Daedalus-class U.S.S. Lovell brings some of Starfleet's keenest technical minds to help, the U.S.S. Endeavour makes a find that could shed further light on the enigmatic meta-genome that has captured the Federation's interest -- if its crew survives the discovery....

Deep within the Taurus Reach, an ancient and powerful alien mind has awakened prematurely from aeons of hibernation, alerted to the upstart civilizations now daring to encroach upon the worlds in her care. With the stakes for all sides escalating rapidly, the alien lashes out with deadly force against the interlopers, propelling the Vanguard crew on a desperate race to understand the nature of the attacker, and to prevent the Taurus Reach from becoming a war zone.

Ancient secrets lie on the fourth planet of the Jinoteur system, and three great rivals are fighting to control it. The Federation and the Klingon Empire want to wield its power; the Tholian Assembly wants to bury it.

But the threat stirring on that distant world is more dangerous than they realize. The Shedai, who ruled the Taurus Reach aeons ago, have risen from their ages of deathlike slumber -- to gather, marshal their strength, and take their revenge.

To keep Jinoteur from falling into enemy hands, the crews of Starbase Vanguard and the U.S.S. Sagittarius must risk everything: friends...loved ones...their own lives. But the sacrifices they make may prove too terrible for them to bear.

With tensions mounting between the Federation and the Klingon Empire, Ambassador Jetanien works frantically on Starbase Vanguard to halt the escalation toward war. Commodore Diego Reyes, the station's former commander, awaits trial for treason, while the shattered mind of his intelligence officer, T'Prynn, becomes the battlefield in a fight for her very life.

But even as matters deteriorate, the discoveries made in the Taurus Reach have captured the imagination of one of the Federation's most promising scientific minds: Dr. Carol Marcus believes she is close to solving a puzzle that will transform her life's work. Meanwhile, an unexpected defection brings a new perspective to the investigation, and Vanguard's Lieutenant Ming Xiong is confronted with an artifact that could be the key to decoding the Taurus Meta-Genome.

But with Operation Vanguard teetering between its greatest breakthrough and a conflict that could engulf two quadrants, its future may depend on the man Starfleet has selected to replace Reyes as base commander: Admiral Heihachiro Nogura.

For Captain William Riker, that choice has already been made. Haunted by the memories of those he was forced to leave behind, he must jeopardize all that he has left in a desperate bid to save the Federation.

For Captain Ezri Dax, whose impetuous youth is balanced by the wisdom of many lifetimes, the choice is a simple one: there is no going back -- only forward to whatever future awaits them.

But for those who, millennia ago, had no choice...this is the hour of their final, inescapable destiny.

Elsewhere, deep in the Gamma Quadrant, an ancient mystery is solved. One of Earth's first generation of starships, lost for centuries, has been found dead and empty on a desolate planet. But its discovery so far from home has raised disturbing questions, and the answers harken back to a struggle for survival that once tested a captain and her crew to the limits of their humanity.

Half a galaxy away, Captain William Riker and the crew of the Starship Titan have made contact with the reclusive Caeliar -- survivors of a stellar cataclysm that, two hundred years ago, drove fissures through the structure of space and time, creating a loop of inevitability and consigning another captain and crew to a purgatory from which they could never escape.

Now the supremely advanced Caeliar will brook no further intrusion upon their isolation, or against the sanctity of their Great Work....For the small, finite lives of mere mortals carry little weight in the calculations of gods.

But even gods may come to understand that they underestimate humans at their peril.
