Fourteen-year-old twins, Cirra and Jace learn that dragons are real when youngling Tonk falls from a magic hole 200 miles above the twins home, too far for the little dragon to fly back. The hole will close in 24 hours leaving Tonk stranded to die. The twins are determined to return Tonk, but the sheriff knows dragons visit earth and his determination to have Tonk is brutal. But worse, Kade, a wanted 7-foot felon, knows the twins have a dragon and will kill to get it. Our heroes are in a dangerous race against the sheriff and Kade. But when they learn that earth and Tonk's homeworld will be invaded by Kreedens, a race of evil giant dragons, the twins charge into what is sure death. They must destroy the Kreeden's invasion plans, outsmart the sheriff, and defeat Kade. To accomplish their impossible task, Cirra takes to the air on the back of a powerful dragon to use her magical weapons in battle against the Kreeden dragons. Except for an amazing surprise by Tonk, she wouldn't have a fighting chance.
