It's 1735. Forrest Harper's life inside the Tower of London consists of three ways to pass the time: chores, chores and more chores. His only friends are the spirited ravens he tends with his father. So when vicious Scottish rebels are captured, Forrest can't wait to prove himself by standing guard. If only Forrest's prisoner hadn't turned out to be the noble and daring Maddy. And if only Maddy wasn't about to be executed . . .
Now, as Forrest chooses between friendship and family, safety and escape, he and Maddy must flee, somehow navigating the cold, dank corridors of the Tower.
