Once there was a gypsy queen who wore on her wrist a chain of six lucky charms - a golden crown, a silver horse, a butterfly caught in amber, a cat's eye shell, a bolt of lightning forged from the heart of a falling star, and the flower of the rue plant, herb of grace. The queen gave each of her six children one of the charms as their lucky talisman, but ever since the chain of charms was broken, the gypsies had been dogged with misfortune. Emilia and her cousin Luka have the gypsy crown, and are travelling with their menagerie in search of the Hearne tribe. They hope that this family, to whom they will soon be related, will surely help release their kin from gaol. Luka and Emilia find the Hearnes horseracing on the Downs above Epsom. But Emilia must compete to win their support. Will she have to give up her beloved mare in exchange for the Hearne family's charm - a small silver horse? And can they escape Coldham again?
