Stranded

this is a maze runner Newt fanfic however, instead of a maze and some other things, i have changed it a little.
Sydney wakes up on a raft that has been washed up on an island, and can't remember anything except for her name. She finds out she is stuck out there with around 50 other boys from the ages of 12-19. The island is surrounded by shark infested waters which would stop them from being able to escape. They don't know who put them there, or why they were there however, they will risk everything to find out.
