A decade ago in upstate New York, art student Emma McCullough walked into the woods and was never seen again. It’s a mystery that still haunts her bucolic university town and her broken family, especially her sister, Haley, whose need for closure has become an obsession. But now, finally, the first piece of evidence in the vanishing has been found: Emma’s bracelet, lodged in a frozen piece of earth at the bottom of a gorge. For Emma’s three best college friends, for a beloved former teacher, and for Haley, the chilling trinket is more than a clue in a resurrected cold case. It’s a trigger.

Then a woman is attacked during an open house, and the connections between the two crimes, ten winters apart, begin to surface. So do the secrets that run as deep and dark as the currents in this quiet river town.

A dead woman’s cherished trinkets become pieces to a terrifying puzzle.

Mickie Lambert creates “digital scrapbooks” for clients, ensuring that precious souvenirs aren’t forgotten or lost. When her latest client, Nadia Denham, a curio shop owner, dies from an apparent suicide, Mickie honors the old woman’s last wish and begins curating her peculiar objets d’art. A music box, a hair clip, a key chain—twelve mementos in all that must have meant so much to Nadia, who collected them on her flea market scavenges across the country.

But these tokens mean a lot to someone else, too. Mickie has been receiving threatening messages to leave Nadia’s past alone.

It’s becoming a mystery Mickie is driven to solve. Who once owned these odd treasures? How did Nadia really come to possess them? Discovering the truth means crossing paths with a long-dormant serial killer and navigating the secrets of a sinister past. One that might, Mickie fears, be inescapably entwined with her own.
