Query: One of the all time greatest books of Science Fiction

I have read this book so many times I practically have it committed to memory. This is probably the best book ever written by Sheri S. Tepper, and maybe one of the best science fiction books ever written. One of the things I like best about it is her use of horses and the parody of the sport of fox hunting. That is only one small part of this book, though. There are numerous sub plots which could make this a difficult book to read, but Ms. Tepper handles it with such facility that it reads very smoothly. I really recommend this book, especially if you like horses, too!
