This is the other fic I got from @auexchange:
Title:
The Telepathy Rulebook Author: VallesMarineris
Fandom: Star Trek (AOS)
Pairing/Characters: Kirk/Spock
Rating: Mature
Word Count: 7300
Summary: When Jim ends up with telepathy after the latest run-in with an unexplained deep space anomaly, he has to learn a few rules.
After all, you have to know the rules before you can break them.
I really loved everything about this - the plot, the characterizations, the journey that Kirk went through as he dealt with his telepathy and of course the K/S was wonderfully done.
