Prime Directive

Starfleet's most sacred commandment has been violated. Its most honored captain is in disgrace, its most celebrated starship in pieces, and the crew of that ship scattered among the thousand worlds of the Federation... Thus begins "Prime Directive", an epic tale of the Star Trek universe. Journey with Spock, McCoy, and the rest of the former crew of the Starship Enterprise to Talin—the planet where their careers ended. A world once teeming with life that now lies ruined, its cities turned to ashes, its surface devastated by a radioactive firestorm—because of their actions. There, they must find out how—and why—this tragedy occurred and discover what has become of their captain.
