The nation watched them fall in love. Now someone's watching them die. Hazel and Marc were paired together on revolutionary new reality TV show Love Synced, in which sophisticated AI matches hopeful lovers based on its perceptive algorithms. But when it came time to say I Do on camera, Hazel couldn't go through with it, leaving her perfect match at the altar, his family furious and the whole TV production in jeopardy. Now all she wants to do is fly home. Instead, she's trapped in a tiny isolated airport that's been ground to a halt amidst a massive snow storm... with her ex and his obnoxiously rich family sitting at the gate with her. But when they start turning up dead, a jilted lover is the least of Hazel's worries – there's a serial killer to catch first.
