What it's about

After thousands of years of searching, humans are about to make first contact with an alien race on a planet whose strange star switches off for centuries at a time. Two human groups wait at its doorstep for the star to relight: the Qeng Ho, free traders, and the Emergents, a ruthless society that enslaves minds with technology. Whoever opens trade with the aliens will grow rich, but first comes betrayal.

Why it's worth reading

It won the Hugo Award and was a Nebula Award finalist. It's one of the great space operas, with an astonishing alien civilization and big ideas about freedom and control.
