Fic Pimp
If anyone hasn't seen firefly_124's wonderful fic Marked Men yet, go read it immediately! It's a BtVS/Harry Potter Crossover fic for summer_of_giles and it features Bad-Magic-Hates-The- World-Ticking-Time-Bomb-Guy Ripper Giles and young Severus Snape. There's a wonderful plot, some hot sex, and although I am not renouncing my love for Ethan/Severus, Ripper/Severus works well indeed.
