I decided not to do a Romance fic this week--I got interested in finding a story involving Snape's home life, and found a one-shot called Retribution, which involves Snape and Tobias, his father.
Seeing as it's a one-shot, there's not much I can tell you without giving away most of it, but you should be able to guess the plot by the title name. It's K+, so anyone can read it, though it is sort of intense. It's also beautifully written, so it really deserves a read. There's only 12 reviews so far, though there should be more...
If you'd just step inside the TARDIS--wait, wrong fandom... Whatever. It's bigger on the inside than the outside, and inside is this link: http://www.fanfiction.net/s/5368353/1/Retribution
