I read it only to finish the series. Average.
I enjoyed all the RAMA series however the first in the series was written solely by Aurthur C Clark seems very unfinished and the next in the series seemed to be more mature. The first is one of the later books published in this genera that had him as the sol writer.
The whole Rama sequel series are good ideas mixed in with bad overwriting and too much attempted character development. While Revealed may be the best sequel, it still manages to suffer from the exact same problems of the last two books. Rama Revealed however, manages to be the most consistent sequel- as in it finds a way to balance its problems and actual good scenes. For example, there are parts where humans are trying to learn to live within an alien species, which for the most part is handled well, mixed in with the threat of a war initiated by the rest of the humans that rains down heavy political overtones. Yet the most heavy handed parts may be the long, scientific and philosophical speeches at the end. The scientific stuff is boring, and philosophical stuff is way too heavy handed. Still, through all the problems, there are some unobjectively good passages detailing exploration of rama. This final novel is a long, overwritten, yet still fascinating piece of science fiction.
