Lilith is one of the few writer's I've found who can write both long and short fics equally well. Not to mention PWPs that might scorch your eyebrows off. ~_^
I especially recommend her two longer fics, L'Histoire d'Obi and Elements (Histoire is BDSM, Elements is AU). I've converted people who swore they'd never read SW with those two. ^_^ She has a rich writing style and a great portrayal of voice, not to mention plot. Highly addictive.
