At first it was a bit dragging but most of what he writes here applies to most married men, and what they must look out for to keep their marriage intact.
This is a solid piece of golden-age science fiction. It has adventure aplenty along with the standard scifi conceits that seem rather primitive by today's standards (a robot controlled with an "infrared pencil," neutronium armor on ships, interstellar conquest). Nevertheless it's great fun.
If you fused Star Trek with Blackbeard the pirate, you'd get Space Vikings.
This novel is truly a modern masterpiece. In structure it's a fusion of Henry James and Graham Greene's _The End of the Affair_. In tone, it's reminsecent of a WW1-era Jane Austen.
The story is exceptionally well-constructed and slowly changes, as you read it. It's full of twists and turns and revelations. But it's basically a quiet, though dramatic, story. Highly recommended.
