Star Trek: Vanguard #4: Open Secrets

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.

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.

Returning from its historic first voyage to the edge of the galaxy, the damaged U.S.S. Enterprise journeys through the Taurus Reach, a vast and little-known region of space in which a new starbase has been unexpectedly established. Puzzled by the Federation's interest in an area so far from its borders and so near the xenophobic Tholian Assembly, Captain James T. Kirk orders the Enterprise to put in for repairs at the new space station: Starbase 47, also known as Vanguard.

As Kirk ponders the mystery of the enormous base, he begins to suspect that there is much more to Vanguard than meets the eye. It's a suspicion shared by the Tholians, the Orions, and the Klingon Empire, each of whom believes that there are less than benign motives behind the Federation's sudden and unexplained desire to explore and colonize the Taurus Reach.

But when a calamity deep within the Reach threatens to compromise Starfleet's continued presence in the region, Kirk, Spock, and several key specialists from the Enterprise must assist Vanguard's crew in investigating the cause of the disaster and containing the damage. In the process, they learn the true purpose behind the creation of Vanguard, and what the outcome of its mission may mean for life throughout that part of the galaxy.

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.
