The only book I know of, which presents cryogenic freezing in a "hard sci-fi" context, and makes it even an important plot point instead of glossing over it, is Fiasco from Stanisław Lem.
In that novel, cryogenic freezing is a very unreliable and dangerous process, and is only used for emergencies. They build it into the cockpits of giant mechas used for engineering and construction projects in dangerous areas, so that in case of an accident the pilot could use it as a last resort. In that time in-universe, the technology to revive them did not yet exist. The author describes that the real-life (so, in-universe, the past) attempts where rich old people were frozen would not work, as all the brain cells will be damaged so that revival would not be possible.
That emergency cryogenic device is described in a very detailed way, and it's quite gory. To preserve the brain mostly intact, it has to be frozen with liquid nitrogen from all sides as quickly as possible, so tubes crash violently through the face and the jaws, to inject liquid nitrogen, shattering most of the skull in the process (while the victim is still alive and awake). Even many decades later, when the technology for revival exists, it is not an easy task. Most of the victims do not survive at all, and the one they can save (in a very controlled, low-gravity environment), still requires extensive surgery, long recovery time, and suffers from severe memory loss.
If I remember correctly, they call it vitrification, as it does not just freeze the body (crystallization would destroy the cells), but they purge all the blood, and most fluids out of the body.
It is used in interstellar travel in such a way, that one of the passengers on the very first interstellar flight is such a cryogenically frozen body, so that they can attempt to perform the very first revival surgery when they left the Solar System.
