instantly engaging and intellectually rigourous,
This review is from: Rollback (Mass Market Paperback)
Sawyer's stories are usually good fun to read. This is no exception. This time around there are two issues looked at. The first, the bones on which the story hangs, is about how SETI might work and its philosophical underpinnings. There is perhaps a bit too much earnest explanation from the characters in some occasionally ropey dialogue.
Far more interesting, however, is that it is also a meditation on the consequences of medical technology: in brief summary, after 60 years of happy marriage, a couple undergo a new medical procedure to rejuvenate them, supposed to return them to how they were when aged 25, but it only works on one of them.
The book approximately alternates chapters between exploring SETI and exploring rejuvenation, and of the two interwoven streams, that of rejuvenation is by far the most interesting, but it could not stand without the other without losing its immediate accessibility. It is this exploration of the ramifications of plausible but as-yet-non-existent technology that marks great sci-fi.
