Looking for a specific fic

[black_k_kat]

This is probably a really obvious story, and I'm just being incredibly blind, but I'm looking for a Snarry story where Snape gets sent to Azkaban, and Harry visits him once in a while, first to taunt him and then eventually to bring him books and visit over the hols. In the end, Snape is allowed out because Harry marries him.

Any ideas, wonderful people?
