Seaton has developed a "Zone of Force" to protect his ship, the Skylark.

But with the Zone up and running, he can no longer control his vessel. Can this new invention help them prevail against the Fenachronians, with their advanced technology... and their determination to conquer the galaxy, starting with the destruction of Earth? And what of DuQuesne and his villainous plans?

Skylark Three is classic space opera at its best!
