Why This Must Be Read: I am really kind of glad that the 'crack' challenge came up so I could rec this story. This is... very au. Very, very au. It also has Horatio Caine as a vampire which is just twelve kinds of genius. It's also incredibly readable in the ways of the best kind of crack. Mary and Marshall are the same and different all at once. That being said, the author did a great job of universe building here and it's worth a read for that alone. (And not just the Crazy Awesome.)
