Coldest Case (Shana Merchant #6)

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 . . .

It's February in the Thousand Islands and, cut off from civilization by endless ice, eight people are overwintering on tiny, remote Running Pine. Six year-rounders, used to the hard work, isolation and freezing temperatures . . . and two newcomers: social media stars Cary and Sylvie, whose account documenting their year on the island is garnering thousands of followers, and thousands of dollars' worth of luxury gifts.

The long-term islanders will tell you Running Pine can be perilous - especially for city slickers who'll do anything to get the perfect shot. So when Cary doesn't return from ice fishing one morning, his neighbors fear the worst.

With the clock ticking to find the missing influencer, a police team is dispatched to take the dangerous journey to the island . . . but Sylvie, his frantic partner, will only talk to one person: newlywed Senior Investigator Shana Merchant.

Where is Cary - and what is it that Sylvie's not sharing? With aspects of the case reminding Shana of an unsolved homicide from her past that haunts her still, she risks her own safety to help. But little does she know that a storm is coming - and if she doesn't solve both crimes soon, she may become the island's next victim . . .
