In Dragons & Machine Guns, Anna and Josef are two dragon riders and self-appointed masters of the sky. After first meeting each other in combat, the two soon become fierce rivals as the war continues to rage on in the world below them. With their beasts they battle each other ruthlessly for dominance of the skies until an incident forces them to work together in order to save both their lives and those of their dragons.

In The Masters Of The Sky, putting the trauma of the war behind her, Anna has now moved on to racing across Europe with her new dragon Lily. However, as the victories stack up she soon finds the need to take on a new challenge: that of the prestigious Grand National dragon racing circuit in America.
