Titan Books continue their series of novels based on classic Star Trek with #24: Corona by Greg Bear. From the stardate, this novel is set in the middle of season three of the show but sometimes the writer makes references to series events as though they were over a decade ago which can be a little confusing.
Starfleet receives a distress call from inside the Black Box Nebula where a science station manned by Vulcans has been studying the nebula and the unusual levels of ybakra radiation inside.
The Enterprise, which has just been refitted at Yalbo, is tasked with finding out what has happened to the scientists. Kirk has two additional problems on the mission. One is a certain Rowena Mason from the Federation News Service who is there to do a report on the ship and crew as well as their interaction with the new computer system. This system is Kirk's other problem, a massive core of six machines with each one containing the complete memory patterns and experience of the six best Starfleet captains. They have the capacity to override Kirk's decisions if they believe he is acting irrationally, against orders or simply failing to execute his duties in a timely manner.
When the ship finally arrives at the station, they find no life signs but there are still four Vulcans there and another 30 in cryogenic hibernation. They soon realise that the Vulcans are under the influence of an alien intelligence which is using them to create a device which has the potential to destroy the universe.
Corona is by far one of the weakest Trek novels in the series to date. It's a small book and a quick read and essentially never gets into the spirit of the original series at all. The characters aren't written badly, but some of the dialogue is rather unbelievable. The whole concept behind the story seems rather absurd and something that would be more at home an Irwin Allen show rather than Star Trek.
All in all, this book is definitely for completists only and like some of the weaker third season scripts, it's certainly not Star Trek at its best.
