In the far future, Earth is a worn-out backwater and humanity is spread across the galaxy on worlds that began as colonies, but now feel like home, each with its own long history of a thousand years or more, and each with its own unique culture. One of the strangest is on Borthan, where the founding settlers established the Covenant, which teaches that the self is to be despised, and forbids anyone to reveal his innermost thoughts or feelings to another. On Borthan, the filthiest obscenities imaginable are the words “I” and “me.” For the heinous crime of “self-baring,” apostates have always paid with exile or death, but after his eyes are opened by a visitor from Earth, Kinnall Darival, prince of Salla, risks everything to teach his people the real meaning of being human.

Only a few know the terrifying truth–an outcast Earth scientist, a rebellious alien inhabitant of a dying planet, a lunar-born human intuitionist who senses the imminent annihilation of the Sun.  They know the truth–but who will listen?  They have foreseen the cost of abundant energy–but who will believe?  These few beings, human and alien, hold the key to the Earth’s survival.

At first, only a few things are known about the celestial object that astronomers dub Rama. It is huge, weighing more than ten trillion tons. And it is hurtling through the solar system at inconceivable speed. Then a space probe confirms the unthinkable: Rama is no natural object. It is, incredible, an interstellar spacecraft. Space explorers and planet-bound scientists alike prepare for mankind’s first encounter with alien intelligence. It will kindle their wildest dreams… and fan their darkest fears. For no one knows who the Ramans are or why they have come. And now the moment of rendezvous awaits — just behind a Raman airlock door.
