I confess I don't read nearly as much fic as I'd like due to time constraints, but here are some favorites, most of which are probably familar to you:
Go Not to Lethe by
queenofthorns. Rated PG. Wonderful study of Lee following the Pegasus arc.
Almost Rhymes With Orange by
mercurial_wit. Rated R. Spoilers through season two. Different views of Lee as he interacts with different characters. Lovely.
Gleaming Auction by
hackthis. Rated PG13. Set during season two. The only fic to ever make me buy Lee/Dee. ;)
Dog Tag Imprints by
goddessspharo. Rated PG13. Short, beautiful piece showing Lee post-"Maelstrom."
Bunk Mates by
alissabobissa. Rated R. Lee, Kara and Helo at the academy. Adorable fic that just feels right, with a humorous and affectionate look at Lee.
Falling by
dionusia. Rated PG13. Set during "The Passage." And it's a perfect "Passage" fic. I love this like pie.
Rewind by
nicole_anell. Rated PG13. Spoilers for "Crossroads." I'm not sure I should even describe this one, it's just frakking brilliant. Lee, Caprica Six, and Kara, as you've never seen them before. A stunning look at Lee.
And if I may be so presumptuous, I thought I'd mention one of my own fics:
The Cost of Living. Rated R, takes place during "Crossroads, Part I."
Thanks for all the comments on my previous post; I still have some to respond to, and plan to do so soon.
