The one that "you send to kill the f***ing boogeyman" wakes up in the future to face the ultimate boogeyman. Somebody PLEASE get this man...a gun!

New Vegas: Sheason's Story by

Is it fanfiction? Is it a novelization? Is it just the disconnected and incoherent ramblings of a man who has finally taken leave of his senses? Yes. This is my attempt at telling a story of New Vegas, but with my own twist, with my character Sheason as The Courier. It's not really "the" story of New Vegas, but it uses the game's plot extensively.
