I'm not a Hero

Tyson Obi was a happy-go-lucky boy living with both his parents until tragedy struck. Suddenly without the love and embrace of his parents, he jumps from foster care to foster care until 18 when he enlists in the army right as WWIII kicks off. Five grueling years later he returns home to discover that running away didn't smooth out his issues. They were made worse because he was the lynchpin holding everything together. With no family to lean on, and no friends to call upon, how will the *REDACTED* fare in a world that evolved without him?
