Another of James Blish's novelizations of Star Trek episodes, this one features two of my favorites, "City on the Edge of Forever" (originally written by Harlan Ellison) and "Operation Annihilate". Blish is much more consistent with his characterizations than in the first volume. Fans should note that this also features the adaptation of the episode "Space Seed", which featured Ricardo Montalban as Khan for the first time.
