Rendezvous with Rama (Rama, #1)

Rendezvous with Rama is a science fiction novel by British writer Arthur C. Clarke first published in 1973. Set in the 2130s, the story involves a 50-by-20-kilometre (31 by 12 mi) cylindrical alien starship that enters the Solar System. The story is told from the point of view of a group of human explorers who intercept the ship in an attempt to unlock its mysteries. The novel won both the Hugo and Nebula awards upon its release, and is regarded as one of the cornerstones in Clarke's bibliography. The concept was later extended with several sequels, written by Clarke and Gentry Lee.
