Fic Title: His Favorite F Word
Author: Summer Reign
Why This Must Be Read: This is one of my favorite canon ships on TV, but there's a shocking lack of good fic for the pairing. This is a nice one - charting the course of their relationship from first meeting all the way to love. It's sweet without being too sweet & fluffy, has a nice Grissom POV, and weaves canon well throughout the series of vignettes.
