Tiger Clinton and his crew return for more adventures in the distant stars!

With their allies from space, they travel first to Mars to see the results of their aid, and then onwards - further into the unknown.

Stumbling across a peaceful planet, however, the explorers and their ship the Tavona find themselves in the middle of an invasion by aliens with superior firepower. Can they use Earth's technology to help? Or are even they outmatched by this unknown foe?

Best known for his Biggles series, Captain W.E. Johns' space adventures are perfect for fans of classic Star Trek and pulp science fiction!
