She lives in the maze /Maze runner and twilight mix/

What if Thomas wasn't the first to live a whole night in the maze? What if there's people who's been put in the maze and not the glade? What happens when Minho is dragging Alby and the gladers see two guys come from the corner and help them and they then see a different figure
but can't see their face since they have a hood? And what happens when the two guys wait at the exit/entrance of the maze and sees the hooded figure from the day before? How do they react when they tell the gladers they've been living in the maze for a couple of months? How do they react when they say that they remember all most everything? Read to find out, oh and I forgot how do they react when the hooded figure is a girl? And she's killed a couple of grievers? You need to read to find out, did I mention it's a Gally x reader?

Hi guys! I wanted to try and put two of my favorite movies together and make a new kind of book tell me what you think and I'll continue
