A short time ago, I declared that TDR52 was up for adoption. I have changed my mind. Having begun to write out my plans for the fic, which were highly detailed, I have decided that I will finish it after all. I expect to finish the next chapter by the beginning of April. After that, I can't say for certain, but I believe having written out my plans has made things easier.
After TDR52, I will be doing something different; I'm not sure what yet, though, as I have a few different ideas competing for realization.
