What to read after This Present Darkness/Piercing the Darkness Set?

In This Present Darkness, something is wrong in Ashton, a small college town where nothing much ever seems to happen. Nothing, that is until Bernice Krueger, a persistent investigative reporter, is thrown in jail after photographing the police chief in a clandestine meeting behind a carnival booth.Bernice knows she's stumbled across something far bigger than a mere political scandal when she compares notes with Hank Busche, pastor of the Ashton Community Church. A suspicious suicide, rash of New Age courses at the college, a mysterious power broker from New York, and a desperate young woman on the run all converge in frighteningly malevolent threat to the town--and to the entire human race.
