it is time (for it to be time) (джен)

Severus Snape never expected to survive the war. But here he is, one year after the Dark Lord's final defeat - one year after Harry Potter's disappearance, presumed death.
As the boy's Last Will and Testament is released, Severus finds himself facing the gravity of his actions, in the form of the secrets hidden inside a cherry-wood box, and scribbled across a leatherbound journal.
