Until they met Ingold, Gil was an ordinary PhD candidate and Rudy was a drifter, whiling away his life riding motorcycles under the California sun. But wizards have a way of complicating things. Ingold brought them across the Void, where an evil known as the Dark threatened to devour civilization whole. Civilization's hopes rested on an infant prince, and to protect him Gil and Rudy had to draw on newfound powers—she as a warrior, he as a wizard.
