Query: I really couldn't put this one down; it was a GREAT book!

The plot was excellant, as were the characters of this must-read book. I do many diffrent kinds of riding, mostly jumping and dressage. I really liked how Robin, the main character, wasn't a perfect rider or a perfect person, amd this made all the diffrence in my enjoyment of this book.Nika is a great character, too, and at first you think she is a really huge brat, until you read along and begin to realize that Nika might not be what she seems.So, this book takes you along a path of people, places, and a certain amount of danger. I loved it, and think both the horse lover or non-horse lover will enjoy it as much as I did.
