Death Cache — Tiffinie Helmer

She shouldn't have played… Gallery owner Tern Maiski has always had a way with men, but the one she gave her heart to disappeared without a word. Now he's competing alongside her and four others in a high-tech treasure hunt, and her pride isn't the only thing on the line. So is her life. He doesn't play by the rules… Geophysicist Gage Fallon's relationship with Tern has been cataclysmic from the beginning. He cared too much, too fast and their passion threatened to consume him. Now he's back on firmer ground and competing in a game that will risk more than his heart. Once their group is dropped off in a remote area near the Arctic Circle, it quickly becomes clear that instead of hunting for treasure, they're the ones being hunted. And the killer is dead serious about caching them in.
