When her father died, Tabby Harper was sent by her Uncle Giles to Greentrees boarding school, where her cousin Merril was also a pupil. At the school. Tabby made an enemy of Charlton, the school groom—who hated her and her mountain pony, Curlew. When Curlew disappeared, Tabby found that he had been sold to a circus. Tabby rescued Curlew, and set out for the only place where he would be safe—the moors round her old home in Larkspring.
