Battlestations! (Diane Carey)

A friend said this was his favorite Star Trek novel, so I had to give it a try. What he liked was also something I liked: a female protagonist who is strong as d resourceful without being Wonder Woman.  Still, it's a little too melodramatic for my taste. The maguffin is a device that has the potential for galactic power and evil (of course) that must be kept from the wrong hands, despite betrayal from several quarters. There is an annoying layer of hero worship over it all, with Spock and McCoy and especially Kirk elevated to god-like levels. It's a good example of the genre, though, better than many.
