Exodus: The Archimedes Engine by Peter F. Hamilton. A cover design/illustration for Random House Worlds for the first in a series of two novels: A space opera set 42,000 years after humanity's departure from Earth in arkships, where the descendants of the first settlers, now powerful and alien "Celestials," rule over the latest arrivals from a newly discovered, long-lost arkship. The story follows multiple characters as they navigate the oppressive Celestial hierarchy, engage in political intrigue within the Celestial courts, and uncover plots that threaten the balance of the Centauri Cluster.
