The people of remote Inishrone, a few miles off the Connemara coast, know not to go to the Island of Horses. Everyone has heard tales of men who have gone and never returned, and some people can still hear the thunder of ghostly hooves. Yet one day young Pat Conroy and his friend Danny MacDonagh head off anyway, claiming that they're fishing for eels. There they find something far more valuable - a beautiful black colt that soon lands them in a world of trouble. Now the boys must return to the island, despite rough seas, along with Pat's frail grandmother who knows of a hidden valley and a secret story. The Island of Horses is fraught with suspense and peopled with unforgettable individuals.
