No One Touches My Sister

You remember the Feaver Code right when Newt's parents are killed the WICKED officer says to take them both and use Newt as a control subject, but what if they didn't.
This book is Newt wandering the streets of Hell looking for his sister because one thing is for sure NO ONE TOUCHES HIS SISTER.
I do not own any of the maze runner characters, I do own the plot, and Even, Kevin, Finch, Megan, Taylor, and Bob.
