A PONY Book/ Last Chance Horse/ By

This book is about a stubborn teen. Kat gets mad easily and goes for a walk by a horse paddock to vent, when along comes a horse who changes her, her life, and her attitude forever. Through the book her relation ship with her sister comes back to life, It's a good book about a horse winning the heart of a girl....... well, mabey a girl winning the heart of the horse. The ending to this is odd, the auther didn't really explain it, but I think that's what she was aiming for, more of a mysterious ending. I would say any one from 10 to 16 would like this book, though it is deffinetly Writen to interest teens more.
