*****Star Trek movies, Paramount's Pocket Books label published literally hundreds of books featuring the characters from the original series and its spinoffs. Unsurprisingly, many of them stunk -- partly because they were rushed into print, partly because many were written by green (inexperienced green, not Vulcan-blood green) authors who would work for cheap and partly because Paramount knew they had a core audience that would buy anything with a pointed ear on the cover whether it stunk or not. Market saturation dried up the stream of books a few years ago, and Pocket editors decided to exercise some more control over the material produced. Part of that was a conscious decision to move some of the series forward through their history -- the overstuffed and meandering Star Trek: The Next Generation series Destiny was one result. But it seems someone at Pocket also decided to put together stories about the original crew as they would have been during the span of the 1960s TV series, in stories such as Troublesome Minds. The Enterprise, entering a new star system, saves a single-person spaceship from destruction engineered by that person's own people. It seems this Berlis is a super-strong telepath in a race of telepaths and his will overwhelms any of his people who may be within his range. His people were trying to prevent that from happening, because a nearby race that had suffered the last time such a "troublesome mind" arose among Berlis' people had vowed their destruction if it happened again. Now Captain Kirk must decide how to prevent war between the two species and stop Berlis from mind-enslaving an entire planet, all the while wondering whether his trusted First Officer Spock, himself a telepath, is being influenced by Berlis as well. Author Dave Galanter has co-written some other novels in the Star Trek universe and knows the feel of a good ST yarn. This is his first original series novel and his first solo, and he does a good job of getting the well-known characters in proper voice and filling their accepted roles. Troublesome Minds doesn't make any monumental changes in the Star Trek universe or signal any watershed moments for the characters, even though they're tested to the limits in many ways. It's a good yarn and whiles away the time, surpassing the wealth of genre fiction that falls short of that modest goal. But asking more than that of a Star Trek book is like wearing a red shirt on an away team: It's a bad idea.
