How amazing would it be to have a dad who's an astronaut? To see him go on rocket launches, live in zero gravity, and fly through space like a superhero? Jamie Drake knows. His dad is orbiting Earth in the International Space Station. Jamie thinks it's cool, and he's proud of his dad, but he also really misses him. Hanging out at the local observatory one day, Jamie is surprised when he picks up a strange signal on his phone. Could it be aliens? Are they closer to our planet than anyone realizes? With his dad in space, Jamie feels he has no choice but to investigate on his own. But when something goes wrong with his dad's mission, Jamie is reminded that space is a dangerous place. He decides it's time to prove that he's a hero, too.
