News of a missing Instagram celebrity brings Senior Investigator Shana Merchant to a frozen island community of just eight people. When the visit turns deadly, her hunt for a killer collides with a cold case she’ll never forget . . .

Cary Caufield isn’t the first man to go missing on an island, but when he doesn’t return from ice fishing, his neighbors still fear the worst. Though Cary and his partner, Anna, run a profitable Instagram account about their year of living on a remote island, they don’t understand the dangers of the ice. The tight-knit community of long-time islanders will tell you Running Pine can be perilous — especially for city slickers who’ll do anything to get the perfect shot.

Newlywed Senior Investigator Shana Merchant takes her own safety into her hands to help, but it soon becomes clear that Cary’s disappearance is more complicated than she first thought. In a place where collaboration can save your life, the islanders are secretive, the newcomers aloof, and there’s evidence of an outsider hiding somewhere in the snow.

At the same time, aspects of the case remind Shana of a homicide she worked back in Manhattan, a murder that haunts her still. As she enters a new phase of her life, she’s compelled to revisit the cold case, plunging headlong into the darkest part of her own past. And when a wind storm traps her on the island with a killer, she’ll need to solve both crimes before she becomes the next victim.

The latest taut, thrilling small-town mystery featuring New York State senior investigator Shana Merchant, and set against the beautiful backdrop of the Thousand Islands, is perfect for fans of Agatha Christie and Ruth Ware.
