Terra , which Neil Gaiman said reminded him of Douglas Adams, Terry Pratchett, and Roald Dahl, launched the novel-writing career of stand-up comedian and BBC Radio 4 Now Show regular Mitch Benn. Now Terra is a couple of years older and back on Earth. She's in hiding. And in Terra's World we find out why. But none of this is known to Billy Dolphin. He's just annoyed that since Terra returned to Earth, Science Fiction has died a death. How wrong could a teenage boy be?
Terra may be back on Earth but the powers of the universe are not finished with her. Her old home faces a terrible threat which possibly only Terra can overcome. Just what is the black planet? To find out first Terra must learn how to survive as there is an alien bounty hunter on her trail. And only Billy Dolphin to help her.
