I found this quiet, multi-faceted story while browsing the AO3 for ST:Enterprise stories.
The Hybrid Child of Vulcan by ChibifukurouPlot summary: Spock is preparing to apply to the Star Trek academy, but before he does he has to come to grips with his hybrid heritage with the help of Christopher Pike and T'pol.
I think what I like most is the way how the different incarnations of Star Trek, ranging from TOS to Reboot!Movieverse blend into each other seamlessly, in a very natural and convincing manner. Also a wonderful, highly endearing take on the individual characters, with just the right mixture of darker notes and a distinct sense of hope.
