firefly marathon watch -- Book fic?

hanging out on july 4rth with the firefly marathon running while i cook, catch up on email, and otherwise laze about.

and it's making me want Book backstory fic.  Does anyone know if any?  He is one intriguing man, and among the myriad reasons i'm sad Firely met such an untimely end is never getting to know much about his story...

Book backstory

huh.  apparently there's an official (as in, written by Zack and Joss Whedon) graphic novel for Book's backstory.
