Matt Cruse is back in the phenomenal third volume in Kenneth Oppel's bestselling, award-winning series—and this time he's heading for outer space. Airborn and Skybreaker, the first two books in the series, have been among our bestselling and most-honored titles, and we think you'll find this one just as thrilling—if not more so. Featuring an international cast of larger-than-life characters, this is adventure fiction at its finest.
