Home is the Hunter by Dana Kramer-Rolls (Star Trek #52, December 1990).

The Federation is late to arrive at the planet Cragon V, and the Klingons have already gotten a foothold with the population. This isn't a good thing with the Organian Peace Treaty, as the Klingons thus have had time to establish themselves with the local populace. Nonetheless, Captain Kirk and his crew are sent to do their best to establish Federation relations with the people of Cragon. It's not easy, as the locals seem to have taken to the Klingons' aggressive ways.

The Enterprise crew gets in a bit of a tussle with the Klingons, and a native is hurt. Hostilities escalate to the ships in orbit until suddenly, just like over Organia, the controls become too hot to handle. It seems that Weyland, the "god" of the planet, has returned. And he's not happy.

After the fighting, one Enterprise crewman, Lt. Garrovick, is dead, and three are missing. Sulu, Chekov and Scotty are nowhere to be found. As it happens, Weyland has transported each of them to a different era of Earth's past, a time apt to their cultural heritage, and inherently very dangerous. Sulu is in feudal Japan, Scotty in Scotland at the time of Bonny Prince Charley as the Scots fought for independence against England, and Chekov in World War II Russia in the Siege of Stalingrad.

The crewmen must fight for their lives, and Kirk must figure out how to convince Weyland to return them to their proper time and place. Before anyone else ends up dead.

It's an interesting plot, and gives feature roles to supporting players, so this is a different sort of Star Trek book. It would have played well as a TV episode, but with all the period costumes and guest stars would have been extremely expensive to produce. But it certainly would have looked cool. The author is obviously a student of history.

And actually, author Kramer-Rolls is apparently many things. Not a prolific novelist, she has written a couple of short stories, often woman-oriented. Which makes it surprising that she does little with Uhura except give her a few funny lines. Chapel doesn't appear at all, except in a brief reference. Apparently the author is not impressed with the Enterprise women. Kramer-Rolls is also a professed "witch" and writer in "neo-Pagan" circles, and author of a few books on cats. Make of that whatever you will.

Another odd bit is the cover, which has pictures of Scotty, Chekov, and....Kirk. Why Kirk and not Sulu? Or why not Sulu also? An odd artistic choice.

At any rate, it's an interesting book, more for devotees of Star Trek characters of historical-reference novels, rather than of the "world" and trappings of Star Trek. Most of the action is set in the past. The book reads very well.
