Just read this in one setting. It was so amazing. I really really enjoyed it. I loved how you wove canon into the story. It was so richly detailed. It was terribly tragic to read (even the happy parts) because of Sirius' hindsight. The Marauder friendship was perfection. Sirius and Remus' relationship was really lovely and you wrote their love and care for each other so well. Also, I really liked how you wrote Lucius as well, sparing Sirius for Narcissa's sake (and slightly, I like to imagine, being a bit cowardly when it comes to murder). Regulus and Snape were brilliant as well, wavering from but not being able to leave the DEs. The brutality of the DEs and Voldemort was horrible and I liked the nasty glimpses we got of it. Obviously, the Marauder's story is always going to be tragic but I think you really wrote the hindsight aspect of this so well. All the mistakes and choices that were made, built up bit by bit and although we want the characters to see what's happening, you perfectly depicted why they didn't. You are such a stunning writer.
