Star Trek: Dark Victory

The Mirror Universe is a dark and twisted reflection of our own, where all that is noble and compassionate is instead cruel and barbaric. Now our universe has been invaded by that other reality's most feared tyrant: the dreaded Emperor Tiberius, the Mirror Universe counterpart of James T. Kirk. Just as Kirk survived his own era to live into the 24th century, so has Tiberius returned from the past to menace a new generation of Starfleet heroes. And only Kirk can stop him.
With Spock, McCoy, and Spotty at his side, and teamed Jean-Luc Picard and the valiant crew of the U.S.S. Enterprise NCC-1701-E, Kirk is propelled into his most personal and dangerous mission yet as he fights to uncover the secret of Tiberius' return and learn the terrible truth behind the madman's nightmarish plans for the Federation.
But how can he defeat an enemy who knows Kirk's mind as well as he knows his own?
|...| [From Library Journal]: In 'Dark Victory', the mirror universe is a dim shadow of the Federation, ruled by a cruel tyrant, Emperor Tiberius. Much to the dismay of James T. Kirk, Tiberius is also Kirk's double and is determined to destroy him, whom he considers to be a weak and embarrassing twin. The action can be a bit confusing for listeners unfamiliar with Spectre, the first title in this series, but it doesn't take long to get one's bearings. Unfortunately, those looking for a satisfying conclusion must wait for the third installment. Shatner is in top form and, along with great sound effects, does an admirable job of resurrecting his signature character. Trekkies of all stripes will clamor for this one, but be prepared to purchase the entire series, as individual titles do not stand alone. Recommended for all sf collections. A few galaxies over, the Star Wars contingent is having its own set of problems. Although Emperor Palpatine is dead, a powerful Ruling Council continues with the empire's plans. Dark Lord Carnor Jax is determined to claim the throne, but he must first eliminate Kir Kanos, the only member of the emperor's elite bodyguard to survive after Jax's treachery toward his emperor and fellow guardsmen. Seeking refuge from Jax, Kanos finds himself allied with rebel forces. But Kanos owes allegiance to no one, and rebel leader Mirith Sinn cannot trust the enigmatic warrior whose loyalty lies with a dead emperor. |...| [About the Author]
