This is an enjoyable and somewhat creepy psychological novella with an interesting idea, and twisted ended. I can't really say more than what the blurb provides without giving away the plot.
From the blurb: "Dr. Jennifer Webb has invented proprietary virtual reality technology that purports to heal psychological wounds by running clients through scenarios straight out of horror movies and nightmares. In a carefully controlled environment, with a medical cocktail running through their veins, sisters might develop a bond they’ve been missing their whole lives—while running from the bogeyman through a simulated forest. But…can real change come so easily?
Esther Hoffman doubts it. Esther has spent her entire journalism career debunking pseudoscience, after phony regression therapy ruined her father’s life. She’s determined to unearth the truth about Dr. Webb’s budding company. Dr. Webb’s willing to let her, of course, for reasons of her own. What better advertisement could she get than that of a convinced skeptic? But Esther’s not the only one curious about how this technology works. Enter real-world threats just as frightening as those created in the lab. Dr. Webb and Esther are at odds, but they may also be each other’s only hope of survival."
