This is the type of science fiction I love: a setting, a premise, mystery and intergalactic space battles. Inherent to the story, which is of a woman who loses part of her memory, there are times of confusion which I experienced but not all of it was based on that. Some details were not described enough, ideas or even a few characters. You knew what their function was, but I still couldn't visualize them since physical details were sketchy, yet I've read enough science fiction and fantasy to not let that hold me back from enjoying the story as a whole. There was nothing glaring which detracted from "The Crystal Memory". I liked the heroine, she was tough and hardy but also emotional in just the right quantities. It was an enjoyable read.
I have the hard cover version which correctly portrays the main character which the one showing does not. When/if you read the book, you'll understand.
