Well, the first book of the new year (2016) also turned out to be one of the better Star Trek novels I’ve read. Assignment Eternity features the return of Gary Seven and Roberta Lincoln (played by Robert Lansing and Teri Garr) on the original series, and has them journeying to the future to prevent the future murder of Mr. Spock.
Like the TV show, we still don’t get a lot of background on Gary Seven, but we get a hootful on Ms. Lincoln, and on their various activities together.
The novel is very well written and characterized, and it’s got a fast moving plot. A fine example of the way Trek novels SHOULD be written!
