Natural Resources police officer, Sloan Cooper, and her partner had just taken down three men preying on hikers in the Western Maryland mountains. Driving back, she pulled in at a convenience store—and walked right into a robbery in progress. One gunshot from a jittery thief was about to change her world. She may be down, but she’s not out. When a woman vanishes, leaving her car behind in a supermarket parking lot, Sloan searches online for similar cases. She finds them, spread across three states. Men and women, old and young—the missing seem to have nothing in common. And the abductions keep happening.
