No one has done podfic of big_pink's fic yet (probably because most of them are virtually novel-length multichaps), but she does have a website where you can find .pdf versions for printing out or reading all in one place. Have you read any of her fic? My favorite is "Red." I was thinking you would probably really like "Fire in the Hole," which takes place in the year after Sam left for Stanford and is heavy on angst and Dean!whump (he suffers a serious back injury) and a really messed up John. Big_pink is an exceptionally talented writer. Her stories are often written in multiple timelines and are complex and fascinating. She does lots of background research. "Fire in the Hole" has a lot of information about mining. The story is written in two timelines, one going forward and the other going backward. It's a demanding but extraordinary read. Here is her site where you can find all her fic in .pdf.
