The Runaway Racehorse is a story about a horse named Whirlaway that has gone missing. Three kids, Dink, Josh, and Ruth Rose, go out to solve the mystery of where Whirlaway has ran off to. They found Whirlaway with his mother eating hay. What they don't know is that it's actually not Whirlaway! The kids go the horse races to watch their friend Sunny who is a jockey. Sunny is the owner of Whirlaway. The race started and Whirlaway came in dead last, which is unusual because Whirlaway is one of the fastest horses out there. Sunny said, "It's as if I'm riding a totally different horse!" It was true! One of the other jockeys switched horses with Sunny without her knowing and used black shoe polish to cover up one of Whirlaway's white spots. I recommend this book to whoever likes mystery books. I couldn't figure out the mystery until the end, but I had an itch someone was messing with Sunny. The author of this book, Ron Roy, writes other mystery books like this one.
