Everything in Peter Day's Head

His head has a mind of it's own.

An introverted college student is dragged to a party by his extroverted imaginary friend, where he meets a cryptic man claiming to be from the future. When the self-proclaimed time traveler recruits him to find his reclusive mob-enforcer cousin and prevent a drug-fueled catastrophe that will wipe out millions, the student is thrust into an eccentric adventure he wants absolutely no part of.
