[These notes were made in 1983:]. Star Trek novels have played with time travel before, but this is the most satisfactory treatment of the theme I've seen. Nonetheless, one can't help feeling mildly tricked or cheated somehow, when an entire narrative line is suddenly wiped out on the basis that time has been changed. It somehow seems to defeat the nature of fiction! McIntyre shares with most female writers that insistence on the essentially emotional nature of the central triad in ST, but unlike some of the others, she is a good enough writer not to insist on analyzing it to death, but instead frames events which display the emotions naturally. One of the better ones in my collection of Trekkiana.
