Slipstream

From publisher blurb:

Not all speedsters are stuck on the ground! The supersonic SLIPSTREAM could fly ever since he could remember. After living all his life being told to hide his abilities and daydreaming about being like the heroes he adored on TV, fate put a challenge before him to save innocent people from violent crime. He had been given a taste of what it was like to help others with his awesome abilities and his path was made clear. If criminals see SLIPSTREAM coming, it's already too late to escape!
