Though
published 51 years ago, I think the book holds up pretty well. Like all science
fiction set centuries ahead, you can be cynical about what these “futurist”
were thinking (like the ones published in the 50s that still had everyone
smoking like chimney’s in the 21st Century), like characters having
two wives (one on Earth, one on the Moon or Mars). That seemed a weird choice
for Clarke. I also appreciated the shortness of this classic take on First
Contact (though not with any actual aliens, but the technology left behind).
The arcs of the characters were satisfying and to the point, and everything was
wrapped up (I guess) in 274 mass market paperback pages.
One
interesting bit: the book was meant to stand alone, although its final sentence
suggests otherwise:
“And on
far-off Earth, Dr. Carlisle Perera had as yet told no one how he had wakened
from a restless sleep with the message from his subconscious still echoing in
his brain: The Ramans do everything in threes.”
Clarke
denied that this sentence was a hint that the story might be continued. In his
foreword to the book's 1989 sequel, Rama II, he stated that it was just a good
way to end the first book, and that he added it during a final revision.
Still,
he and Gentry Lee pen a total of four novels set in the Rama universe,
including 1991’s The Garden of Rama, and 1993’s Rama Revealed (Lee would write
two more novels set in the same universe without Clarke, 1995’s Bright
Messengers and 1999’s Double Full Moon Night).
