I'm really enjoying this AU K/S fic: Leave No Soul Behind.
The AU is that there's EPAS - Emergency Personnel Ambulance Service - which is like super badass emergency medics in space, and they're affiliated with Starfleet but they're not military and Starfleet is being all incompetent about dealing with Nero. Spock joined EPAS instead of Starfleet and at the beginning of the fic, Kirk transfers to it and winds up under Spock's command. The relationship builds really slowly - I'm up to chapter 5 and I just got to the sexy part.
I really like it. The characterizations and the world-building are both great. That's one thing that's been really hard to find: fanfic where the writer really gets the characters. I love how they write Spock's dialogue in particular. Not many people can pull that off. It's so good I'm willing to overlook the occasional misuse of apostrophes and the PADDs problem.
