Cardinal

From publisher blurb: Meet Cardinal, the genius engineer by day, heroic vigilante by night! Ok, so he fights crime in the daylight as well, but his job as an engineer for Meridian Enterprises keeps him quite busy most daytime hours -- in the nighttime, Cardinal seeks to protect the innocent, defend the defenseless, and prove to the world the corruption residing inside his own employer's organization... perhaps even clear up to the main man himself, the starling darling of Summit City: Dr. Erick Schuster!
