City of Speed (Battle Dragons #2)

In the city of Drakopolis, dragons and humans have co-existed for centuries. Dragons burn the city's garbage, taxi its busy citizens from place to place, and even compete in vicious underground battles for ganglike kins.

But the dragons also compete in legal sports, like the spectacular aerial races that draw in cheering crowds by the thousands.

Abel is at just such a race when he witnesses something terrible. A long-shot competitor surprises the crowd by winning the relay -- but then flies into a destructive rage! Someone in the city is experimenting on dragons, dosing them with a dangerous serum that provides speed and strength at the cost of the dragons' health.

Abel must find out who's behind the experiments and end them. But with his sister working for the kins, and his brother in the city's secret police, will that mean he has to face off against his own family?
