Frank Harper Mysteries Series by Greg Enslen

Ex-cop Frank Harper doesn't want to get involved. Harper is visiting the small Ohio town of Cooper's Mill, trying to reconnect with his estranged daughter and a grandson he's never met. But he finds the town gripped in fear-two young girls have gone missing, taken in broad daylight from a busy street. And the police are coming up blank. But once Harper is drawn reluctantly into the investigation, he'll stop at nothing to find the girls. And he doesn't care who gets in the way.
