Katie makes a sacrifice to save the life of a disabled racing colt—but will it all be in vain?

At Willow Run Thoroughbred Farm, horses are born and bred for racing. When a much-anticipated bay colt endowed with the farm’s finest racing blood is born with terribly twisted legs, the obvious choice is to put him down. He’d be lucky if he could stand and nurse, let alone race. But thirteen-year-old Katie can’t stand the idea. Born with one of her legs almost an inch shorter than the other, she wonders what would have happened if her parents had felt the same way about her. What if they had given up on her entirely when they realized she couldn’t be a prima ballerina?

Desperate to save the colt’s life, Katie works out a deal with the farm’s owner and becomes the proud owner of Willow King. Can she help him overcome the odds and claim his place as the racehorse royalty he was born to be?
