Thirteen-year-old Cassidy Drake wants nothing more than to race with her best dragon, Ranga, in the annual Great Texas Dragon Race. Her mother was a racing legacy, and growing up on her family's dragon sanctuary ranch, Cassidy lives and breathes dragons. She knows she could win against the exploitative FireCorp team that cares more about corporate greed than caring for the dragons.
Cassidy is so determined to race that she sneaks out of her house against her father's wishes and enters the competition. Soon, Cassidy takes to the skies with Ranga across her glorious Lone Star State. But with five grueling tasks ahead of her, dangerous dragon challenges waiting at each one, and more enemies than allies on the course, Cassidy will need to know more than just dragons to survive.
