Thirteen-year-old Eric Johnson never wanted to move out of Philadelphia.But the untimely death of his parents left him little choice in the matter and dropped him in the farm country outside the Lehigh Valley, an hour away from his old home, living with an aunt and uncle he barely knew. Used to the big city with its constant action and excitement, Eric found the slow pace of the rolling farms frustrating. He kept looking for ways to move back to the city, back to his friends and all his familiar activities. But when Eric helped a tall, blond-haired stranger escape from a pack of wild dogs, he took the first step in an adventure that took him out of the mundane world of Eastern Pennsylvania and dropped him in the middle of Norse mythology; right at the heart of a centuries old war between the Norse Gods and their ancient enemy, the Frost Giants.
