The spirit that was almost visible in the white pony was that of a top-class show pony, fleet and beautiful beyond the singing of it ...

Shantih is lame, and she's not getting better. It's all Jinny's fault. Desperate to find an answer, she goes to a nearby riding school, hoping they'll be able to help.

They can't. It is the very worst sort of school. The ponies are broken down, miserable and dragging themselves through their long days but one in particular tugs at Jinny's heart. Jinny can see the glorious show pony Easter once was.

Jinny cannot leave her there, but neither can she afford to buy her. She must also find a way to help Keziah, the mysterious woman who helped Jinny paint the Red Horse, and who needs Jinny's help

Somehow, Jinny must work out how to rescue Easter, and face what happens when people and ponies grow old.
