First, lack of time. I needed to cut back on my existing projects to keep some of them viable. This one was the fic I was least happy with, so I cut it.

Second, unhappiness with the work. I started it before I really got into Harry Potter and came to realize I didn't make the post-war situation messed up enough. The fic needed to be overhauled and I just didn't have the time or interest to do that.
