Title: Untitled, because I can't think of anything suitable. Suggestions most welcome at any time.
Rating: NC-17 for smut, language and violence.
Summary: The Hellmouth has been quiet while Spike and Xander rebuild their lives, but after two local sisters disappear from their graves in unvampish circumstances, things rapidly go from mildly disconcerting to apocalypse in just 12 days. And the enemy? They're angry, they're in agony, they're everywhere, and they're deader than Spike and Angel put together.
