Severus Snape and the Revival of the Living Dead

Ever wondered what's a Death Eater gathering like? What does Snape do when spying? What may be on Aberforth's mind? AU story, romance with AU character, Snape POV, rated M for reason, occasional foul language and repeated description of violence, non-descriptive references on drug-use and later lemons make it best for audience above the age 18.
