Except for some erstwhile comic bits, this novel, a children’s book, was pretty much Third Season in quality. It was also, technically, the very first Star Trek tie-in novel.
The Enterprise has been on a VERY long mission and is called to respond to a distress signal from a star system that hadn’t been properly explored by the Federation. McCoy, however, is more concerned about the overworked crew suffering from “space cafard” from the monotonous routine of this particular mission.
Luckily, the author managed to get Kirk, Spock, and McCoy’s personalities down pretty well. Uhura is also a lot like the TV show, though Scotty, Sulu and Chekov are all over the place. The story is a bit of a combination of the episodes “Omega Glory”, “Patterns of Force”, “Bread and Circuses”, and a bit of “Friday’s Child” – decidedly lesser concepts all in the Star Trek firmament.
Trekkers and trekkies will probably enjoy this, but otherwise unless you’re a kid, I wouldn’t bother with it.
