The Captain's Daughter by Peter David (Star Trek #76, December 1995).

The Enterprise-B, captained by John Harriman, is called to Askalon Five by a repeating distress beacon. A team beams down to the planet to investigate the call, as sensors are having trouble getting through to the surface. Ensign Demora Sulu, on the away team, comes back as a berserker, naked and screaming, and attacks the captain. Harriman shoots her in self-defense, and Demora Sulu is dead.

The Ensign's father, Captain Hikaru Sulu, is devastated by her death. So is her godfather, Commander Pavel Chekov, who slugs Captain Harriman at the memorial service. But it is Captain Sulu, so soon after losing his mentor James T. Kirk, who struggles most with the situation. He recalls how he met Demora's mother, and raising the precocious young child. And, he decides he must do something to find out how she died on a deserted planet.

Peter David stories are always a gem. The plot is advanced bit by bit, something that will be important in Act III is revealed and introduced in Act I, and there is a crispness and light touch to the writing. The stories are well-constructed, the actions logical and human. It was soon after this that I stopped buying the Star Trek books, and a lot of it was because of the poor quality, though that's not a problem with this one.

Like all of David's books, this one is highly recommended.
