United Cherokee States of N'America, the Knower

Conner Gray gradually realized as a child that he had a unique and unsolicited gift/curse/skill: he knew things. If he's asked a question, any question, he knows the answer. And he's always right. And he doesn't know how he knows.

One day Conner, now a 26 year old professional proofreader, receives an article from the Center For Disease Control in which nine experts ask what they think is an academic question: "Is it possible that a virus could sweep the world so quickly that it would annihilate up to 90% of the human population, and if so, how soon could that happen?" The wording of the question triggered an involuntary response and he 'knew' the answer: yes! And he knew when: just 181 days after he reads the article. BUT the experts' answer is "no". He 'knew' they were wrong. But who would believe him instead of nine experts?

He called the only friend he could trust to believe him. Together they set out on a quest to survive the coming apocalypse. 177 days. And counting.
