Finally got around to posting this review:
I'm not as regular sci-fi reader and besides Watership Downs or Animal Farm I haven't read many books where all the characters were animals and I thoroughly enjoyed this novel.
Fox paints a vivid, complex, outer-space world with enough detail to make it interesting but without getting into Tolkien-like minutia sacrificing detail for content. Throughout the book I could see the world he envisioned and he crafted the story in such a way that walking, talking, human-like animals seemed natural in it.
The story line is a captivating mystery. Through the book I kept wanting to know more, and I enjoyed the way the author wove separate yet related elements into a nicely blended outcome. I didn't expect the book to be so suspenseful and full of intrigue and I really enjoyed each new surprise when they came along.
The characters really made this book enjoyable though. Although the hero(ine?) is certainly a likeable yet tortured complex character, I felt drawn to some of the supporting cast. I enjoyed watching, as the story developed, these characters growing, becoming more complex, and ultimately moving the story to its culmination.
Definitely worthy of five stars, and I recommend this book to just about anyone.
