Litany of the Long Sun — Gene Wolfe

(The Book of the Long Sun #1 - #2 omnibus) Litany of the Long Sun contains the full texts of Nightside the Long Sun and Lake of the Long Sun, that together make up the first half of The Book of the Long Sun. This great work is set on a huge generation starship in the same future as the classic Book of the New Sun. The story of Patera Silk, a devout priest whose destiny is wrapped up with the gods he serves, takes place within the Whorl, a vast, cylindrical starship that has traveled for generations and is crumbling into disrepair. Through a strange and amazing series of events, Silk finds himself descending to base thievery, running afoul of a notorious crime lord, befriending a cyborg soldier, and encountering at least one of the gods of Mainframe.
