Emerald is a woodland fairy who has been sent on an urgent mission to the Kingdom of Thisseldar. Her traveling companion is an old and wise tortoise named Cinnamon. A chance meeting with Princess Emery and Prince Ryan results in a high spirited adventure. Together, they must out-smart some clever trolls to find "That Which Has Been Hidden" and save all of Fairydom. A chapter book for 7 to 10 year olds. It is the third book in the Thisseldar series and finds eight-year-old Princess Emery and her brother, Prince Ryan, eager to help their newly found friends: a fairy and a tortoise. Suspenseful capers through the castle result in near catastrophe as the four try to outwit the troll, Over Bent, and his three companions. It's a free-for-all as to who will find "That Which Has Been Hidden," and who will claim it as their own. Thisseldar books do not have to be read in any particular order.
