I really enjoyed the writing in this one. I want to read more by Gilden. He really got the voices of Spock, McCoy, and Kirk down so I didn't need any "Kirk added" or such. And the details Gilden adds, the bits of what it's like to be an officer, to be a friend, to be loyal to one's vision or to one's employer... excellent. The woman is extremely (but not ridiculously) intelligent, brave, and competent, and is referred to by her surname (a nice change). And the speculative bit was creative, and the humor and the omission of too much page-turning adventure... oh, I could go on.
Instead, let me share some stuff I marked:
"Enyart's, famous for fine dining across the galaxy."
"*Enterprise* time and Starbase 12 time were within two hours of each other so warp lag [akin to jet lag] was not much of a problem."
"Sharpening one's wit [ie, the banter between Spock and McCoy] was a welcome diversion, even from reading, three dimensional chess, or a workout in the gym."
"We are generally self-conscious dancers... but in the other arts the Vulcans' love of logic does not preclude our appreciation of beauty."
"That evening after his watch, after dinner, Spock went to his cabin - to meditate, he said. Kirk hoped it would be as satisfying to him as a well-deserved nap would be to a human. Kirk had eaten with him, but conversation had been sparse. Sometimes it was like that after a mission. Everything had been said, and they would not think of new things to say till time insulated them from their most recent trials."
