"To Keep Calendars in the Absence of Time" by

First read: 20-02-2008.
Notes: 17.350 words, that's to say, almost a novel. This Snupin, fully DH-compliant, takes place, naturally, in the afterlife. It's not a very traditional afterlife that to which Snape wakes up to, though. It looks a lot life Spinner's End but... SO brilliant, a lot depends on the mysteries here so I won't go into details but this is the best Snupin I have read.
