In the hidden dragon sanctuary of Wyrmroost, Celebrant the Just, King of the Dragons, plots his revenge. He has long seen the sanctuaries as prisons, and he wants nothing more than to overthrow his captors and return the world to the Age of Dragons, when he and his kind ruled and reigned without borders. The time has come to break free and reclaim his power. No one person is capable of stopping Celebrant and his dragon horde. It will take the ancient order of Dragonwatch to gather again if there is any chance of saving the world from destruction. In ancient times, Dragonwatch was a group of wizards, enchantresses, dragon slayers, and others who originally confined the majority of dragons into sanctuaries. But nearly all of the original Dragonwatch members are gone, and so the wizard Agad reaches out to Grandpa Sorenson for help. As Kendra and Seth confront this new danger, they must draw upon all their skills, talents, and knowledge as only they have the ability to function together as a powerful dragon tamer. Together they must battle against forces with superior supernatural powers and breathtaking magical abilities. How will the epic dragon showdown end? Will dragons overthrow humans and change the world as we know it?

War has come to the dragon sanctuaries of the world and nowhere is the danger more intense than at Wyrmroost. After a humiliating defeat at the hands of Kendra and Seth, Celebrant, King of Dragons, prepares to unleash his fury and take control of his native preserve. Armed with information from a new ally Ronodin, the dark unicorn, Celebrant seeks a legendary talisman the dominion stone. However, the powerful stone is protected by a cursed castle. Upon entering the castle fortress, an unyielding power strips all magical beings of their power and forces Celebrant to take his human avatar form. Kendra and Seth must enter the cursed castle as well. The race is on. Will the two young caretakers rally enough support from the creatures of Wyrmroost against the greatest threat the magical community has faced in ages? Can they foil Celebrant's plan and beat him to the mighty dominion stone? Or will all hope be shattered by the wrath of the Dragon King?

Cursed by the Key of Forgetting, Seth has lost all memory of his past—his relationships, his experiences, and who he really is. For now he will align with his new mentor, Ronodin, the dark unicorn, who takes him to the Phantom Isle, the secret gateway to the Under Realm. Though Seth is not formally a prisoner, Ronodin wants to use him and his shadow charmer powers for his own dark ends. Kendra is frantic to find her missing brother, but the quest will take her and her companions, including Warren, Tanu, and Vanessa, far from Wyrmroost to Crescent Lagoon—a recently fallen dragon sanctuary made up of many islands and underwater domains. Its caretaker has regained a foothold on one of the islands. If Kendra and her friends can save that sanctuary, they might uncover the answers they need to rescue Seth. With each sanctuary the dragons overthrow, Celebrant, the Dragon King, comes closer to the dawn of a new Age of Dragons. With the forces of darkness on the march, can Kendra and her allies gather enough power to win the epic dragon war?

Who will win the battle between Dragons and Giants? As the war with the dragons intensifies, all eyes are turning to Titan Valley for help. A dragon sanctuary unlike any of the others, this one is home to enslaved dragons ruled by the powerful Giant Queen, one of the five monarchs of the magical world. In addition, it houses the arena for the Titan Games, a series of gladiator-style battles presided over by none other than Humbuggle, the demon who stole Seth’s memories! Seth is seeking for his memories. Kendra is seeking for Seth. And everyone is seeking to stop the dragons from taking over the world—everyone but Ronodin, the dark unicorn, who has his own devious agenda. In the monstrous battle between giants and dragons, who wins? In the race to retrieve a magical talisman that could help win the war, can Kendra trust Seth? Will they find the answers they desperately need in a realm of trolls and titans? Or are more betrayals imminent?

The magical world teeters on the brink of collapse. The Dragon King, Celebrant, has united the dragons into a vengeful army, and only a final artifact stands in the way of them unleashing their fury against humankind. With established allegiances shifting under the strain, Seth and Kendra find themselves in desperate need of new allies. Seth must face his most dangerous quest—the fulfillment of his pledge to the Singing Sisters. With only Calvin the Tiny Hero at his side, Seth needs to collect the pieces of the Ethergem, including the stones from the crowns of the Dragon King, the Giant Queen, and the Demon King. Halfway across the world, Kendra finds herself torn between her duty to Dragonwatch and her desire to rescue Bracken. Can she challenge Ronodin’s control of the fairy realm without leaving the five legendary dragon slayers to be hunted by Celebrant and his sons? Left behind at Titan Valley, Knox and Tess must survive the aftermath of the Giant Queen’s fall. Will the secret crown in Knox’s possession prove too much for him to handle? In this fifth and final volume of Dragonwatch, our heroes make their last stand at the hidden Kingdom of Selona.
