Andy Weir built a two-decade career as a software engineer until the success of his first published novel, * The Martian,* allowed him to live out his dream of writing full-time. He is a lifelong space nerd and a devoted hobbyist of such subjects as relativistic physics, orbital mechanics, and the history of manned spaceflight. He also mixes a mean cocktail. He lives in California.
