Well, this was like reading two books simultaneously. One concerns a world in which Sam has been a slave since his father sold him age eleven. Dean buys him from the slave market where he would otherwise be destined for a work camp. Seraph Castiel gets in on the act partway through the fic.
The other story as told in the chapter notes, describes the author, her husband and cats and the trials and tribulations of writing this epic. I enjoyed both stories immensely but did get a little distracted from the main event. Anywho, 5 stars all round!
