Chevalia is an enchanted island where ponies and horses rule, its magic powered by eight golden horseshoes hanging in the royal castle. But the horseshoes have been stolen and must be found before Midsummer Day or the island will lose its magic ...A Unicorn Adventure! When the second youngest Princess Pony, Honey, enters the forbidden Cloud Forest, Pippa and Princess Stardust know they must follow her. They find out Honey's secret - she has made friends with a unicorn, and knows where the unicorns live in the forest. Pippa is awestruck. But when Honey's unicorn friend mentions a magical tree in the centre of the forest, Pippa suspects that one of the golden horseshoes might be hidden there. Braving fire-breathing dragonflies, she and Stardust summon all their courage and head deeper into the forest, hoping to see the unicorns, and maybe even find a golden horseshoe, too. The fourth in a fabulous series of six books filled with spooky Night Mares, unicorns, Princess Ponies, and rip-roaring adventure. - from Amzon
