When Allie Caldwell gets a rambling middle-of-the-night call from her very excited aunt Mel, she initially curbs her concern; her aunt has always been a bit eccentric, after all. But when Mel disappears before telling anyone what has her so worked up, Allie drops everything -even her better judgement - to fly to Ann Arbor and find her. In the ensuing days, Allie inexplicably ignores her gut instincts (and some weird dream-based warnings from angry flying squirrels) and accepts help in the search from her aunt's handsome, enigmatic neighbor George Bennet. In order to discern how virtual reality goggles, innovative migraine research, hidden treasure, attack drones, and a neighborhood trellis are all connected to the case, they'll need to survive bungled bids of help from Allie's well-meaning brother, hidden agendas from multiple neighbors, constant interruptions from Mel's itinerant Chihuahua and his exuberant pit bull puppy pal - and even some attempts on their lives.
