The Jamie Drake Equation
Christopher Edge (2017)

Jamie’s dad is an astronaut and is 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 civilization with a message for humankind ?

This starts as a lightweight adolescent book about a boy and his relationship to his father. Then it gets darker and intense. Only to be resolved by a rather magical deus ex machina.
