What is your favorite piece of writing you've ever written? What's the premise?

I've been writing since I was 13 and I have a ton of stuff in my "vault" but there's always one story or concept that every writer can go to and be like, "This is what I can do."<br><br>So - what is your favorite thing you've written? No judgement (I've literally linked the 4 other threads about this so we can't be judged) and what was the premise of your work?<br><br>Please share :)
