Just a year after her mother's murder, Raven Black writes a letter, her godfather's idea, to her father in Azkaban. After weeks of letters, Raven finally meets her father and surprises more than one person with a promise she makes to him. After years of visits and wishing for something real, Raven fights to set her dad free.

Petunia responds to the overwhelming responsibility given to her in blankets and a parchment letter. Severus wallows in self pity, then, possibly, remorse. Both of them are subjected to Dumbledore's manipulations because both of them caused a common loved one way too much pain. Maybe saying sorry to those green eyes will help the past forgive them.
