Hot Sleep: The Worthing Chronicle (1979) is a science fiction novel by American writer Orson Scott Card, part of his Worthing series. Card's novel The Worthing Chronicle (1983) covers some of the same ground.
It's one of his earliest works, so it isn't as well-produced as some of his later stuff, but it explores some very interesting ideas.
(This story began life as a different novel called Hot Sleep. Having read both, I honestly can't remember which parts are in which version, but Card himself says he considers The Worthing Saga to be the official version)
(hint: in Card's story, cryotech created a dystopian, not utopian society)
Here, let me chime in with another piece of Card's writing advice, as convincingly retold by Jo Walton:
"My C shelves begin, controversially, with Orson Scott Card, who was one of my favourite authors for a long time but whom I can no longer read. I started reading him with Hot Sleep and A Planet Called Treason in the early 80s, and I stopped in 1997, so I have read absolutely everything up to then and nothing since. I stopped reading him because he said in his book on how to write that the best way to get readers engaged was to have appealing innocent characters and torture them, and after that I kept seeing that he was doing that and it kept jerking me out of the story."
