Joe Dilly has a secret way with horses - and with fire. His kid brother, Roy, knows about both secrets, but he's not telling. Not when he and Joe hire on at the Bar None - a ranch that has a few secrets of its own.

After years on the run, Roy wants to settle down - and more than anything he wants a pony of his own. A wild, very special pony at the Bar None that runs like the desert wind.

If Roy can break that pony, he can keep her. But the past is catching up, and as terrible things begins to happen at the Bar None, Roy will have to face the truth - the truth about Joe Dilly, and the secret of the fire pony.
