The Jamie Drake Equation by Christopher Edge

A cosmic adventure for anyone who's ever looked at the stars, from the award-winning Christopher Edge.

How amazing would it be to have a dad who's an astronaut?
Rocket launches, zero gravity, and flying through space like a superhero! Jamie Drake's dad is orbiting the Earth in the International Space Station and Jamie ought to think it's cool but he just really misses him...
Hanging out at his local observatory, Jamie picks up a strange signal on his phone. It looks like alien life is getting closer to home.
But space is a dangerous place and when his dad's mission goes wrong, can Jamie prove that he's a hero too?
