Art Rec: HP/SS, slash
Despite the title, "Harry Potter and Severus Snape", by Glockgal, is absolutely lovely. It's also been around for a while, but alas, I am lazy and had never poked about in Glockgal's site before. This has been thoroughly remedied now. :D

The image is password-protected, but all you have to do is answer a pop-up question. It is slash, so I suppose there should be a warning for that, but both participants are fully clothed and there's nothing explicit; it's a "relationship" type slashiness, not a smutty-type slashiness. Go, go and see now!
