Actually, while Sarek
does cover portions of their courtship and marriage, I don't think it includes their first meeting. Spock's World
does offer a version of it, though. Demons
by J.M. Dillard also has flashbacks to their courtship, though I don't know if it shows their first meeting. Of course, these versions aren't all compatible with each other, and I'm not sure if any of them are.
