The Tavona is called to action once again!

When signals from space summon Vargo, the Professor joins the crew to conduct more research into the alien races their adventures have introduced to them. This journey takes them into the unknown reaches of the galaxy, trying to find a planet which has shifted orbit between solar systems. On their way they face snake aliens, tiny meteorites, and worlds where the air itself is deadly.

The eighth instalment in Captain W. E. Johns' science fiction series brings more classic sci fi adventures from the legendary creator of Biggles.
