North Country, Book 1: The Riders of Redrog
Liz is a young girl who wants nothing more than to be a warrior. Raefon is the dragon version of the ugly duckling. What does such an odd pair have in common? An ancient bond that has connected them since before their birth. As a girl, however, Liz has no chance of becoming a rider. These two destined companions must somehow join forces before their powerful bond drives them insane.
