I was always slightly embarrassed about loving this book. But I've decided that there's nothing wrong with "chick-lit in space" (And let's be fair it pre-dates the latest rash of "boy meets girl with compications" by about 40 years!)
Sara is a likable lead and Harlan just the sort of hero you want - strong, brave, intelligent, passionate....you know the deal.
The idea of the human race and other creatures being used to feed more advanced races is actually pretty grim (and rather clever). And the zany meld of space flight and pusedo-middle ages works well.
This is fun, romantic read in an interesting sci-fi setting.
