What's the Frequency, Madison? [Worm, Time Travel]

Synopsis:

October 9th, 2009. It was a date that had burned itself into Madison's brain through months and years of obsession. It was the date when she had taken that first step to ruin. That date when she'd taken the coward's way out and clasped hands with the devil. She could fix it, though. What was the brain, if not a series of waves? Waves could travel through space and time, if you knew how.

And she knew how.

Notes:

This was my NaNoWriMo attempt for 2022 and the first one I every did "for real" by starting at the start of November and getting to the 50k word threshold by the end of the month. Now I'm going back through and editing the chapters so that I can post it in a few "real" places including on AO3. It will probably get some amount of continuation, as well.

Originally, I posted this in my drafts thread under the title Frequency, but the long title was always What's the Frequency, Madison? It's a reference to the REM song (which is about an older person trying to understand the younger generation) which is also a reference to that time Dan Rather was attacked by a time traveler from 2265 who needed to stop his television station from broadcasting signals directly into his brain.
