"Dark and gloomy Fog Island is shrouded in mystery. Many have ventured there, but no one has ever returned to tell their tale. But one day, Finn and little sister Cara are blown off course and get cast away on its murky shores. However they soon find out that things are not always as they first appear on Fog Island... Will they ever come back? And if they do, will anyone believe what they have seen?"--Jacket flap.
