There are actually two fics that I'm going to recommend here.
They have both completely blown me away with their storylines and incredibly rich characters.
1). Destiny's Pleasure
by Lena7 - To tell you the truth anything
Lena writes is pure gold. This is not an exaggeration. She writes with such passion and raw intense emotion it's beyond talent with her, it's pure artistry. Such stories as Trapped and Insatiable Desire and many many more are just insanely gripping and flawless. Destiny's Pleasure is completed now but when she was writing it I was checking daily for an update, it's just beyond perfect. It is currently located in the Abyss. You will not be disappointed. OH it also has the best twist of any story I have ever read. I was literally yelling at the computer unable to hold in my excitment ...needless to say I. loved. it!! Her portrayal of Max is better than anything I have ever read.
2) Death is a Playground
by darkmoon - Ok if you have been lucky enough to had read her series The Domestication Of Zan in the completed section of the UC board you already are aware of this girls brilliant mind. Death is a Playground is currently in the Abyss and if you even peak at it you will be drawn in so fast it will make your head spin. Truly one of the best stories I have ever read darkmoon is to me on a whole different level than the rest of us. She will have you crying on moment and laughing the next. The hero of the story FLiz will just have you glued to the computer screen with her heartbreaking depiction of a woman who has the weight of the world on her shoulders. This should be for sale in a book store somewhere. darkmoon has written these characters that we love so much far better than the writers on the show. Her play on words is just on a genius level. I again recommend anything she writes but Death is a Playground is beyond amazing ...it's just perfect.
