Rama

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, incredibly, an interstellar spacecraft. Space explorers and planet-bound scientists alike prepare for mankind's first encounter with alien intelligence.

In 2130, an alien spaceship, Rama, entered our solar system. The first product of an alien civilisation to be encountered by man, it revealed many wonders to mankind; but most of its mysteries remained unsolved.… Sixty-six years later, a second approaching spacecraft was detected; four years on, the Ramans are definitely returning. But this time, Earth is ready. And maybe now, with the arrival of Rama II, some of the questions posed by Rama will at last be answered.

In the year 2130 a mysterious spaceship, Rama, arrived in the solar system. It was huge, but empty - apparently abandoned. By the time Rama departed for its next unknown destination many wonders had been uncovered, but few mysteries solved. Only one thing was clear: everything the enigmatic builders of Rama did, they did in threes. Eighty years later the second alien craft arrived in the solar system. This time, Earth had been waiting. Now Rama II is on its way out of the solar system.

Years after the appearance in the solar system of the immense, deserted spaceship, Rama, a second craft arrived, destined to become home for a group of human colonists. But now the colony has become a brutal dictatorship, terrorizing its own inhabitants Nicole Wakefield, condemned to death for treason, has escaped to New York. There she is reunited with her husband, but pursuit is not far behind and they are forced to flee to the subterranean corridors of New York inhabited by the menacing octospiders.
