There was a book I read a long time ago, maybe 20 years or so. It starts with a young woman waking up in the future, and slowly starting to learn what's been going on since she's been in cryogenic hibernation:
Life extension technology has been developed, but it's both expensive and imperfect. Only the rich have access to it, and it keeps them alive, but leaves them horribly deformed. People call the deformities the "yuppie effect". Society has devolved into at least something of a dystopia by this point, including labor programs literally involving digging holes and filling them up again.
Her father had been a researcher working on life extension. It's believed that he managed to get it right, but somehow he died and his research was lost.
At some point, he talked about the critical formula with her, that no one has been able to replicate since then, but she wasn't really paying attention, since that was his area of interest, not hers. But the people who found her believe that the secret is still somewhere in her brain.
There are two factions. The "good guys" want to use a brain-scanning machine on her to find the secret and surgically erase it from her brain so that the rich and powerful can't use it to further their dominance over everyone else. The "bad guys," of course, want to use a brain-scanning machine on her to find the secret and use it. Eventually, the bad guys get ahold of the secret and start to use it, but it turns out that
there was a flaw in the formula and it ends up killing the people who use it instead of prolonging their lives and fixing the "yuppie effect."
Does this sound familiar to anyone?
