Drake and the other Dragon Masters go to the island of Kapua seeking a Sea Dragon needed to help stop the evil wizard Astrid's dangerous False Life spell.

The Dragon Masters have two tasks: track down the newly hatched Lightning Dragon, and find his destined Dragon Master, a boy named Carlos, and convince him to trust them--but somebody else has dark plans for this particular powerful and wild dragon.

The Dragon Masters have defeated the evil wizard Maldred, but not before the Kingdom of Bracken was devastated by Naga, the earthquake dragon; now Drake and his dragon, Worm, must appeal to the spring dragon, Fallyn, who is their only hope of restoring Bracken before its people starve--but Fallyn lives deep inside a secret fairy world, and Drake must pass a series of tricky tests before he can even make his appeal.

"Congratulations! You have been chosen by the Dragon Stone! Here is your official Dragon Master guide. Inside you will find facts about the Dragon Masters and their powerful dragons, review secret notes from me and other wizards, study world maps, learn the history of the Dragon Masters, and more! - Griffith of the Green Fields, Royal Wizard to King Roland of Bracken." --

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?

Diego is under the spell of the wizard Maldred who wants to control the Naga, an enormous dragon that lives deep within the Earth, and plans to use Diego to steal the two keys necessary for that purpose; the first key is guarded by Argent, the silver dragon, and Jean his dragon master, so Drake, Bo, Carlos, and their dragons travel to Gallia to try and stop the theft and break the spell on Diego.

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...

The wizard Astrid is planning to cast the False Life spell which will bring to life the bones of giant ancient beasts and allow her to conquer all the kingdoms; in order to prevent her the Dragon Masters must find the Wind Dragon, the final dragon needed to undo the spell--but that dragon and her Dragon Master are captives, and it is up to Drake and his friends to rescue them, and hope they are in time to stop Astrid.

The Dragon Masters discover that a Shadow Dragon named Chaya and his Dragon Master Aruna are responsible for a huge shadow stretching across the sky, but how do they have so much power and why are other wizards around the world losing theirs?
