Pairing: Lorelai Gilmore/Luke Danes
Fic Title: The Essential Light of Need
Why This Must Be Read:
This is an AU from the end of season 6, in which April is in an accident. Her hospitalisation brings Luke and Lorelai together again - but it's not smooth sailing for them.
I've found that I'm very picky about Gilmore Girls fanfic; of all the many I've tried, there's only been a handful that I've really liked. This is one of those few. It's definitely angsty, even tear-jerking at times, but it also has some lovely relationship moments.
There is also a sequel, named "The Long Road Ahead"; while I don't think it's as good as the first story, it's still well worth checking out.
