Okay, this was a novella, so it was a slim and quick read. Unfortunately this is the text's biggest drawback. We're introduced to street smart Katerina and her brother, but before we can care about either of them or their relationships, cancer hits and they get frozen. The story doesn't really progress once Katerina wakes up. Effectively we spend a small amount of time on her discovering that she's in the future before the book ends.
This is not to say that this is a bad book. It isn't, there is a great plot and some interesting characters in there, struggling to be told, but the book is far too short, the exposition far too heavy and the relationships far too shallow in order to for me to want to invest further. It could do with a lot of expansion as the ideas are there and I would love see this as a novel.
In short I would have enjoyed this more as a longer and better edited read.
