A catastrophic pandemic ravages the globe, reducing the human population to extinction levels and cleansing the world of mediocrity.
A doomsday prepper, a molecular geneticist, a journal-keeping loner, and a martial arts-trained nerd survive the disease that annihilated almost everyone else on the planet. Despite the miles between Kansas and California, Texas and Arizona, the four share a connection.
They realize that not dying was the easy part.
