Summary
When 33-year-old Katlyn Harp suddenly vanished, her twin sister Heather knew almost immediately that something was very wrong. The two were inseparable, best friends, daily confidants, and the kind of twins who never went a single day without talking. So when Katlyn’s usual morning selfie never came, her phone went dark, and a suspicious text claiming she had “needed a break” surfaced, Heather’s gut told her this wasn’t a woman walking away… it was the start of a nightmare.
