I didn't think I'd like this story when I first started reading, but as it turns out I really enjoyed it. The man's description of slowly going to sleep as the cryo process was carried out was quite interesting and made sense, whether it could be done that way or not. It's quite believable. Being 20 light years away from the nearest human wasn't appealing, though.
The male space traveler seems to have no problems waking up and thawing out as he is supposed to, but the severe headache is one part that he doesn't like. It's when the female, Terra, begins to wake up that the problems start. Imagine having medical problems with only two people on board the space craft and no medical help is available and the closest help is 20 light years away. It's a scary, panicky thought. I won't write any spoilers, so you'll have to download this story and read it for yourself to see what happens.
Even though this story is science fiction, it's written in a way that is very believable. If a scientist told me this is how you freeze and thaw someone in space, I'd believe him/her. I would just like to know a bit more about the characters and what is in store for them.
