Eirik Gumeny is the [insert superlatives here] author of the cult-favorite Exponential Apocalypse series. He’s written for WIRED, Cracked, Nerdist, SYFY, a couple of medical textbooks, and even The New York Times once. Born with cystic fibrosis, Eirik still has cystic fibrosis, because that’s how genetic diseases work. In 2014, he received a double lung transplant and technically died a little. He got better.
