Eight-year-old Drake is snatched up by the King's soldiers and taken to the castle where he is told by the wizard Griffith that he has been chosen to be a Dragon Master like Ana, Rori, and Bo--and his first task will be to discover whether his dragon, Worm, has any special powers.

When the king decides to take the dragons to Arkwood to visit Queen Rose, Rori, Drake, and their dragons are left behind--so when the evil wizard Maldred attacks the castle riding a giant four-headed dragon that spits poison, the two young dragon masters and their dragons are forced to defend the castle by themselves.

The prime Dragon Stone seems to be dying, and that means that the connection between the dragon masters and their dragons is also fading, so the six dragon masters must located the hidden stone, and learn what is causing the problem before their telepathic connection is completely gone.

Lalo the baby lightning dragon has been taken by Eko, a rogue Dragon Master, who ran away with her thunder dragon years before--now she is back looking to make allies of the other dragon masters, and so gain control over all of the dragons in Griffith.

The Dragon Masters are still reeling from the desertion of Rori and her fire dragon Vulcan, when Mina, a Dragon Master from the far north, arrives with a problem--King Lars needs a fire dragon to defeat the Ice Giant who has frozen his kingdom; and so the Dragon Masters set out to find Rori and convince her to help.

Drake has a dream about a new dragon that is somehow trapped in a cave, so Drake, Ana and their two dragons set off to find the Rainbow Dragon's dragon master, Obi, and together they must rescue Rainbow dragon, Dayo, from Kwaku, a giant spider, who spins a deadly web.

Having taken the silver key, the evil wizard Maldred is after the gold key, which is protected by the Gold Dragon and her Dragon Master, Darma, but by the time Drake and Rori get there, Eko and her Thunder Dragon have seized the gold key--so together the three dragon masters, follow her through the portal to Maldred's tower, but without their dragons will they be able to stop Maldred and his deluded helper, or even save themselves?

Not all of the wizards who were freed from Maldred's time-trap were good wizards; one of them, Astrid, is planning on working a spell that will bring to life the bones that lie scattered in the Fortress of the Stone Dragon, bones that belonged to creatures much bigger than dragons--and when his friends are turned to stone it is up to Drake to find a way to save them, including his own dragon, Worm.

Drake's friends Mina and Caspar, their dragons, and Worm were trapped in stone by the evil wizard Astrid who has stolen their dragons' powers, but Drake himself was saved from a similar fate by Astrid's sister Hulda; now because of his strong connection with Worm, Drake is able to help his dragon to break free, but to free the others they need the assistance of three other dragons--a lava dragon, a sea dragon, and a wind dragon--and they have to do...
