Good. Everything was fast for me (And I'm not talking about the fic, but about how I had to read it). It was... How should I say... Fascinating? Incredible? Amazing? No idea, I'm not good at choosing the right words to say. It's just about enjoying.
In the end. The fic, as I said, there is no exact word to describe it. Compared to the series, this is a more complex story. Also that it is more serious and covers more negative themes, talking about loneliness, death and fear itself (something that few shipp fics are dedicated to, which is why I am very fond of yours)
Anyway, there is much more I can talk about, but it would be repeating the same thing, but with different words.
My dear. You are magnificent.
