I'm not sure why I kept this particular book (I got rid of most of my Star Treks years ago). The science was too fuzzy for me even though the theme of how difficult it is to correct actions was on target. The secondary characters were distractions to me for the most part. The "villains" (Dr. Mordreaux and Ian Braithwaite) were pretty two-dimensional. It was nice to see Sulu given air-time, but too bad he was made to seem so wishy-washy. And really, a dying Kirk was able to overpower Spocks mind? I'm rereading my fiction collection to see if I want to keep it on my bookshelf. This may go: I'll see when I'm finished weeding my shelves.

One of the earliest and best Star trek novels, in which Kirk is killed in a horrifying fashion by an escaped madman. Spock, in the efforts to track down the madman and discover why this happened, discovers that the killer has set into motion an experiment that will throw the entire universe into a deadly time warp in less than a century. With the aid of an earlier, sane time-travelling edition of the killer, Spock discovers that Kirk's death must be prevented in order to save the universe. An enthralling, well-constructed story, given added impact by McIntyre's careful studies of character motivations and the freedom to study them in new situations that is afforded her by time travel. Sulu, in particular, is well-handled here. But all the characters, and a few new ones, are dealt with intelligently and humanely. ( )

One of the first Star Trek novels, and a darn good one. The story revolves around a scientist who devlops a time travel device and the resulting entropy that ensues from its use. ( )
