Из тьмы приходит утро

The AU of Prisoner of Azkaban and the one where Harry finally finds out the full truth about October 31, 1981. Harry struggles to rebuild himself after the shattering events of his second year. He will finally learn the truths he needs to know...but they're hardly going to be pleasant ones.
The title is from Swinburne's The Garden of Proserpine: Pale, without name or number,
In fruitless fields of corn,
They bow themselves and slumber
All night till light is born;
And like a soul belated,
In hell and heaven unmated,
By cloud and mist abated
Comes out of darkness morn.
