Lem, a human, and Mikey, an A.I., are piloting the first ever faster-than-light speed ship when they find themselves twice as far as they meant to go, and without any fuel for a return flight. The two of them communicate with Earth using tiny faster-than-light-speed drives, which carry information for Mikey and questions for Lem from his kids. As they work together to solve the problem, they forge a friendship that could change the course of human history, all while trying to answer the question “how did this happen?” And more importantly… “Why?”
