One and a half thousand years, and life is as complicated as ever.

Merlin, the legendary King Arthur’s mysterious magician, is immortal. As Arthur lay dying he promised to return. Merlin is holding him to his word. Forever young, forever waiting, Merlin lives an unassuming life in the city, keeping his identity and abilities secret from his friends. It's a long and lonely road, but Merlin is a patient man.

It's now the 21st century and when the earth begins to groan with earthquakes, Merlin knows the situation is anything but natural. An eruption is imminent, but something—or someone—is forcing this volcano to erupt. Merlin must use his concealed talents and practiced charisma to save a town of innocent people before disaster strikes. He has the power to thwart a catastrophe—if time doesn’t run out first.
 Suave. Good-looking. Flair for languages. Magic powers.
Immortal.

Merry Lytton, or Merlin as he was once known, has been waiting for the return of his friend King Arthur for centuries. It's an eventful wait: only weeks ago, he stopped a wicked plot to magically erupt a nearby volcano. Merry's latest worry is the revelation of his immortality--his modern-day friends are a little too curious. They do not need to know he has a history that could fill a library.

Unknown to Merlin, the organization Potestas is furious at his geologic meddling, and an enraged member of the group is determined to wreak vengeance. For the first time in Merlin's ancient life, he must confront an enemy that is vastly more powerful than himself. Battling high in the skies and over mountain peaks, will Merlin's foe leave him breathless—​forever?
