Here is my idea. I hope you like it, however I'm more than sure someone is going to kill me for it. It's going to be kind of strange to begin with, but I hope to turn it into a romance fic by the end. A Luna/Snape slash. If you want to know why I picked them, it's because Snape is fascinating because there is so much she (J.K.) doesn't say about him, yet gives enough info to keep us curious. And at this point, Luna hasn't beed developed much, so it's kind of like a blank slate.
Snape is keeping up his rouse as a double agent, and is given an unusual assignment by the dark lord. Come up with an invulnerability potion, or an immortality potion, anything too keep my death eaters alive! Were his exact words. However, something goes terribly wrong..
Luna is an outcast. Though having a great adventure with Ginny and her friends last year, she hardly considers herself "one of them". Not that it matters. That Harry seems...well she feels strange when she thinks of him. She has no hope though. Especially now that the dark lord is "out" and is quietly building his forces. No ones knows it, but Luna can feel it. Something she has been able to do since her mother died, she can't explain it but something is different with her, and it's not just her obsession with the quibbler. Everything is about to be put into fast forward for this quiet oddball though..

Well I don't think I want to type more, lest I give anything away? Making assumptions already? Curious at all? Hate the very ideas I've placed here? Review this and tell me what you think!
