A young rider. A secret, jealous rival. Who will win?

Cassie Piotrowski is alarmed. After excitement peaks when she and her new hunter mare, Snowdrops, are on track to be the Children's Hunter Equitation Champion, the thirteen-year-old equestrian's confidence vanishes after discovering a threatening note and then two more in her show trunk, warning her she better stop winning or else ...

But the determined young rider is surprised at how quickly she caves into the mounting bullying. Wishing she could safely tell someone about the intimidation, Cassie carries the secret alone, doing the best that she can but unconsciously messing up the easy-to-win classes.

Will Cassie find the courage to compete and make her dream of earning the championship come true, or will she hopelessly give in to the threats of a mystery tormentor?
