Nightshades

Alex McKenna is the new Special Agent in Charge of the Chicago office of the Bureau of Paranormal Investigations-the division tasked with investigating crimes involving shades. Or vampires, as they're more widely known. Children have been going missing, and agents are routinely being slaughtered. It's up to McKenna, and some unlikely allies, to get to the bottom of the problem, and find the kids before it's too late.
