Dragor's Fire — Ken Johnson

Riding on a meteor, a blob of black goo from the planet Decay crash lands on an unsuspecting earth only to find the secret ancient burial cave of all dragons. The slimy glob clones itself into a hideous black dragon and calls himself Dragor. Holly Johnson, Beginner Magician, and Fangor, her dragon friend, are once again called upon to save Fairyland, this time from the evil monster determined to take over the world for his own kind. Much larger, stronger, and with a breath of flame called blackfire, Dragor sets out destroying villages and eventually threatens Holly's hometown, Bicuspid on the Root Canal, itself. Holly, with her talking toy bear, Taddy Boy, has to use all the power given to her by King Molar of the fairies, the help of the newborn dragons, and the Guardian of Dragons to try and stop the wicked alien... but will it be enough?
