Green Rider, by Kristen Britain

I really liked this book. It was exciting and there is a lot of adventure throughout the book. This book is extremely clean.
The main character is a girl, Karigan, who enters into the messenger service of the king. As she tries to deliver the message she runs into a lot of trouble and learns a lot about herself. At the end she has to decide if she wants to go back home and be with her father or stay to work for the king and be a Green Rider.
