Snape goes to Valhalla with his tiny, tiny stick

My Snape-goes-to-Valhalla-by-mistake fic, The Hall of Heroes, is now up at Fiction Alley! Slightly revised to make it compliant with HBP - even so, it makes rather big assumptions about Snape's essential goodness which may or may not be canon-compliant, but I can't help that.

Summary: In which Severus Snape finally gets his just deserts - or does he?
Contains mistaken identity, Giants, horned helmets, mead, "the Ballad of Severus the Small and His Tiny, Tiny Stick" and the final fate of all good Death Eaters.

And yes, I do know that the traditional Valhalla of Norse legend is actually where human heroes wait around for the Final Battle in which they ride out and slay Giants. That's why I don't actually call it "Valhalla" at any point in the story. But it just keeps slipping out when I try to publicise the thing...
