Five years have passed since Avalon returned to the real world and faced both the loss of magic and a full-scale invasion. Through great effort and sacrifice, Avalon disappeared once again, a solemn victory with a high price. Torn asunder from a giant landmass into an archipelago of islands, Avalon's throne is usurped by Mordred, the immortal bastard child of Morgana le Fay. With an army of undead wraith knights at his command and the children of the Lords of Avalon at his side, Mordred threatens the entirety of Avalon's existence.

Standing in his way are the children of the Gil-Gamesh: Hunter, Rose, and Ashley. Since their father's death during Avalon's Reclamation, these three have resisted Mordred's reign at every turn from their new home in the ruined Elven city of Alfheimer. Along with the Holy Order of Shield Maidens and the Hîldrägo Boquè, an elite corps of Elven warriors, they fight back to reclaim the throne for the rightful heir, King Bowen, and to restore Avalon to the people. But even now, Mordred schemes to bring down the resistance by constructing an ancient magical artifact...The Prometheus Engine. Only the immortal king knows its secrets and the power it will bring him, no matter the cost. Hunter and his siblings must race across the archipelago to uncover the engine's secrets and discover the truth behind Avalon's Reclamation.

The story continues in THE PROMETHEUS ENGINE: Book 4 of the FOREVER AVALON Series!
