The Eye of the Red Dragon: The Guardians of Elestra (Volume 5)

Derek and Deanna and their friends accompany Iszarre to King Barado's castle for a picnic that ends with Iszarre arguing with a peach tree about giving him a second piece of fruit. Their search for the fifth moonstone starts with a trip to Tobungus' home, the Torallian Forest. That means that Zorell must meditate to find a happy place, and Tobungus needs to feed his shoes flipper juice to increase his dancing abilities. If Tobungus seems weird, his friend Rorrdoogo and the Mushroom wizard Bohootus are stranger yet. But, the real action takes place in the Dragon Realm where a young king finds his way, and his color, and an old dragon gets his mojo back. At the end of their adventure, as usual, Derek and Deanna are left with more questions than answers. Who was this friend who betrayed the older dragon, and where did all of the purple dragon wizards go?
