I really liked Yesterday's son and Time for yesterday. novels books they're some of my all time favorite Tos Books. You also might like Sarek too by A.C. Crispin. No spoilers but I thought the stories were excellent. I've re-read several times. Greg Cox wrote a TOS / Voyager crossover Novel a few years ago that kind of ties in with these books too. Somewhere in his book he said A.C. Crispin books in spired this story.
