The Jamie Drake Equation

Jamie’s dad is an astronaut. This is a good thing – because how cool is that? And a bad thing – because he’s going to be orbiting the Earth for several months and Jamie already misses him badly. Doing his homework at the observation lab one night, Jamie inadvertently picks up a weird signal on his mobile phone. Could it be from an alien civilisation with a message for humankind, a message that Jamie has to get to his father before it’s too late? But how do you rescue an astronaut without heading into space yourself?
