An enormous cylindrical object has entered Earth’s solar system on a collision course with the sun. A team of astronauts are sent to explore the mysterious craft, which the denizens of the solar system name Rama. What they find is astonishing evidence of a civilization far more advanced than ours. They find an interior stretching over fifty kilometers; a forbidding cylindrical sea; mysterious and inaccessible buildings; and strange machine-animal hybrids, or “biots,” that inhabit the ship.

The Forever War (The Forever War, #1) by Joe Haldeman

A reluctant conscript drafted into an elite Military unit, Private William Mandella has been propelled through space and time to fight in the distant thousand-year conflict; to perform his duties and do whatever it takes to survive the ordeal and return home. But “home” may be even more terrifying than battle, because, thanks to the time dilation caused by space travel, Mandella is aging months while the Earth he left behind is aging centuries…
Eon (The Way, #1) by Greg Bear
From the blurb:
The 21st century was on the brink of nuclear confrontation when the 300 kilometer-long stone flashed out of nothingness and into Earth’s orbit. NASA, NATO, and the UN sent explorers to the asteroid’s surface…and discovered marvels and mysteries to drive researchers mad.
For the Stone was from space–but perhaps not our space; it came from the future–but perhaps not our future; and within the hollowed asteroid was Thistledown. The remains of a vanished civilization. A human–English, Russian, and Chinese-speaking–civilization. Seven vast chambers containing forests, lakes, rivers, hanging cities…
