Dark victory - William Shatner

Moments after the dramatic rescue of the Enterprise-E from Mirror Universe infiltrators, Kirk finds himself locked in deadly battle with Tiberius - an enemy who knows Kirk's mind as well as he knows his own. From the nightmarish landscape of Mirror Universe Earth, to the joys of impeding parenthood and marriage to the woman he loves, Teilani of Chel, Kirk is propelled into his most personal and dangerous mission yet as he fights to uncover the secret of Tiberius's return. With Spock, McCoy and Scotty at his side, and teamed once more with Captain Picard and the crew of the Enterprise-E, Kirk discovers an unexpected enemy deep within Starfleet itself. As he fights to expose them, his search becomes a deadly obsession that threatens all he holds dear, drawing him inexorably to a conclusion that will forever change his life and his understanding of the universe. With the fate of two universes hanging in the balance, this is Star Trek storytelling at its best!
