A young David Marcus meets Mr. Spock during a Klingon raid on a distant federation outpost years before the events of Star Trek 2: The Wrath of Khan. This could have been a big flop, due to playing with old continuity, but it turned out pretty good. I enjoyed it.
Another wonderful story, telling a bit about the younger life and bravery of David Marcus, his courage in the face of danger shows true lineage, although he doesn't know it yet.
