The Scorch Trials is my favorite book in the trilogy so I really like this piece by Allinablur. A spoiler-filled quote is at the bottom so read at your own risk!
“Good.” Rat Man absently picked up another piece of paper and turned it over. “At that point, the Scorch Trials will have begun. The rules are very simple. Find your way to open air, then head due north for one hundred miles. Make it to the safe haven within two weeks’ time and you’ll have completed Phase Two. At that point, and only at that point, you’ll be cured of the Flare. That’s exactly two weeks—starting the second you step through the Trans. If you don’t make it, eventually you’ll end up dead.”
