Two extraordinary children with very special qualities are chosen to save the secret world of Gidon and prevent the destruction of mankind by Sclarvete the Nightwitch. After discovering that Sclarvete has regained her powers, the children find themselves in a perilous adventure fraught with danger as they journey to find the Hall of Whispers in order to renew the enchantment on the Fountain of Ice. Encountering things no human has ever seen, they battle their way through every obstacle, helped on their journey by a fairy goblin, a blue panther and the amazing Giggletwinklesteps. Can good win the day against evil? And what does a fifty pence piece have to do with everything? This beautifully illustrated book from Elizabeth Revill will appeal to all children aged between five and nine.
