Drago

As teenagers, Jason, Lucy, and Magda were instrumental in winning the first war between dragons and wizards in the Kingdom on Hector (Dragon Time). In the second book in the series (The Gathering), they fought to repair a magic rip between the worlds of Drago and Earth, before it could destroy both worlds. Now they have to traverse the world of Fairy during a war between elves, saving who they can, and try to get back to stop the war on Drago before it leads to the destruction of the many breeds of the dragon that Drago is named for, and hopefully, let the three of them settle down into normal domestic life.

But normal life is never easy for teenage Wizards and Dragons
