Alex Adams knew college would be full of new challenges: living with her roommate Jenny, a crush on her roommate's boyfriend Arthur and navigating a whole new social scene, but a magical war wasn't part of the plan. Instead, strange visions draw her towards new friends, and their lives are changed forever when they learn that magic is returning to the world. With the return of magic comes the return of an ancient enemy of humanity, the Sídhe, magical beings from another world set on enslaving Earth.

The line between legend and history blurs as terrible forgotten truths come to light. Their only allies are the three-thousand-year-old mages Merlin and Morgana, who must teach them to control their magical gifts if anyone is going to survive. The scars of an ancient war bleed anew as Alex and her fellow mages face their futures.
