Publisher's summary
Trapped within E-Space, the Doctor, Romana and Adric are searching for a Charged Vacuum Emboitment — the gateway back to our universe. It's like looking for a needle in a haystack.

Then, by pure chance, a brand new CVE rips into being. Its makers are the Farrian, a warlike race who have the technology to break into E-Space. They have come to invade and plunder this new territory, and the riches of the planet Ballustra are their first target.
