The Dragon's Eye

A couple of hundred years in the future, there is a struggling Chinese colony on the planet of a double star not too far from Earth. One of their suns is the blinding and carcinogenic Dragon's Eye, which requires them to cover up and wear hats when it is in the sky. The colony has a huge, burdensome debt to Earth, and there is a question of rebellion and rumor of a possible declaration of independence. So a courier is sent in, disguised as a native, to bring back a highly placed spy—or at least his brain, so information can be recovered and Earth's interests preserved.
