Sundog, by B.N. Ball

Been a while since I visited our VAST collection of (mostly) inherited vintage science fiction novels. While I was happy to see many of them find new homes via eBay, the majority still reside with us. Slowly but slowly we're working our way through them, I love the covers, and the breathless cover copy. This guy's head looks all xplody, but maybe in a good way?

This1969 paperback from Avon was 1st American printing, Prev. 1965 British publication.

The front says: "A power from outside our universe had imprisoned mankind in the solar system -- until one man dared to confront the captors."
The back cover says: "An unthinkably vast, invisible, and absolutely impenetrable screen imprisoned man within the solar system. Cut off from the stars, men applied their ingenuity to themselves, setting up a world of total control -- where even dreams were programmed."

Hm, that sounds a lot like a very popular current SF novel that's got a lot of attention!

This was Brian N. Ball's first novel. He's since produced a number of sf series and standalone novels, even including a couple of Space:1999 novels.
