Magnus is a New England bridge troll on a mission: to find his only living brother Radley, who is hiding out on a pirate ship in a Florida amusement park. Trouble is, Magnus has no idea how to get to Florida - until he meets Jenner, a 10-year-old boy with a plan. Join Magnus and Jenner as they jump a train down the Eastern seaboard, run into an alligator hunter and flee from the law. Will they find Radley or will Magnus return to New England alone, or worse yet, be caught by horrible humans?
