A Deepness in the Sky

After thousands of years searching, humans stand on the verge of first contact with an alien race. Two human groups: the Qeng Ho, a culture of free traders, and the Emergents, a ruthless society based on the technological enslavement of minds. The group that opens trade with the aliens will reap unimaginable riches. But first, both groups must wait at the aliens' very doorstep for their strange star to relight and for their planet to reawaken, as it does every 250 years

Then, following terrible treachery, the Qeng Ho must fight for their freedom and for the lives of the unsuspecting innocents on the planet below, while the aliens themselves play a role unsuspected by the Qeng Ho and Emergents alike.

More than just a great science-fiction adventure, A Deepness in the Sky is a universal drama of courage, self-discovery, and the redemptive power of love.
