In the aftermath of Morgan le Fay's war on Camelot, the once great kingdom struggles to rebuild. Knights scour the world, attempting to restore the Round Table's glory by locating Avalon and the Holy Grail before the dreaded Black Knight can do so first.
Vivienne, Merlin's former apprentice, toils in secret day and night on orders from the Lady of the Lake to build an aeroship. The Lady has seen the future and promised that the ship will ensure Camelot's knights succeed in their quest.
But when a company of knights goes missing―including Owen, Vivienne's brother, and Marcus, her beloved―Vivienne changes the plan and commandeers the aeroship for a rescue mission, altering the fates of all involved. Now, the Lady sees danger in Vivienne's future. And for Marcus, either betrayal or death.

By day, 17-year-old Vivienne is the lady-in-waiting to the future queen Guinevere; at night, she is an apprentice to Merlin. The famed wizard has given up magic and is teaching her the secrets of alchemical machines. Guinevere and Arthur are to be married soon, and Vivienne is kept busy during the preparation for the wedding. Her feelings for Marcus, a knight in training, are a welcome distraction to her double life. Suddenly, Morgan Le Fay returns to attack Camelot and claim the throne. Vivienne soon learns that magic always comes with a price. At the exact moment she begins her attack, Merlin's protection spell begins to expire, and he must be careful not to resort to magic.
