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?From the author of The Many Worlds of Albie Bright.Cover illustration by Matt Saunders.
