I have read this book probably seven or eight times already. It's a wonderful, slightly episodic story of the crew of a hard-working spaceship, just trying to get along in the universe. What makes it so fabulous are the characters and their relationships. Highly recommended for anyone who loved the tv show Firefly.
What really surprised me about this book is the positive tone in the story. This time sets it apart from most other stories. And still the author manages to create tension and excitement. It's a very good SF story and I can't wait to read the sequel!
