This Is Goodbye, Gravity and it's sequel We All Welcome Change. by formerlyknownas.
It's an Oli Sykes (of Bring Me The Horizon) fanfiction, but don't be put off, it doesn't read like a fanfiction at all. Some of the most stunning writing i've ever read, well worth the read, but be warned, it'll keep you up all night because you don't wanna stop reading. I love it.
http://www.mibba.com/story/_102451/_165779/ THAT! MOST AMAZING STORY EVER! It's extremely well written and you have no idea what is going to happen. It's amazing and you HAVE to read it! It's called forgotten. The main character is Caden or Cadey. Cadey has a crush on the most popular guy in school, Jon. But Cadey thinks Jon won't give him the time of day. It's a really good story and you should read it RIGHT NOW!
