Graphic novelist and Visualizer Willow Tate can draw images of beings from the neighboring realm of magic, possibly "drawing" them from their world to ours in the process. So why has she foolishly decided to make the hero of her next book a fire wizard? Is that why the strange fire bugs suddenly appear at the East Hampton fireworks display and then start heating things up in and around the little Long Island town of Paumanok Harbor? These miniature arsonists are causing a whole lot of trouble, and when a baby swallows one and begins to cry flames, Willy knows she needs professional help to put a damper on the situation. This time the Department of Unexplained Events sends a "fire fighter," Piet, a man whose very presence prevents fires from starting. With a tabloid reporter focusing his attention on Willow's activities, and a science teacher determined to turn the fire flies into an energy source, Willow will be hard-pressed to keep the town's secrets safe. Not only does she need to find a way to send the fire flies back to their own dimensions, she and Piet-who are starting to generate some heat of their own-have to track down a real arsonist who seems determined to set the area ablaze...
