Ashleigh's dreams are in tatters....

Ashleigh Griffen is thrilled when the owner of the horse farm where she lives puts her favorite horse, Wonder, into training as a Thoroughbred racer. Ashleigh has spent the past year turning the sickly filly into a beautiful, healthy yearling.

Ashleigh knows Wonder could be great, but Wonder dislikes her harsh new trainer. Soon she's bucking and disobeying all his commands. Ashleigh is heartbroken when the trainer says Wonder is untrainable...useless.

Even worse, Wonder doesn't seem to know Ashleigh anymore. One day after Wonder fiercely throws her, Ashleigh becomes afraid of her own horse. Maybe the trainer was right after all-maybe it's time to give up on Wonder....

Read Thoroughbred and experience the love and friendship between a determined girl and a very special filly.
