One sunny day in California, Jessie is hugging her nine-year-old son, Dylan, goodbye at the airport. He's travelling by himself, all the way across the country, to visit his father, Jessie's soon-to-be ex-husband, and his grandparents. Her heart breaks, but she puts on a brave face and gives her son one last wave as a flight attendant leads him away. Several hours later, Jessie gets a frantic call from Dylan's grandmother in New York. Dylan is missing. In a second, Jessie's world turns upside down. The AirTag she'd stuck in his backpack says he's still at LAX. The airline insists that he was picked up at JFK by an elderly couple claiming to be his grandparents--but Jessie's in-laws insist they haven't seen him. Dylan has disappeared into thin air. At the same moment, miles away, in Toronto, a train operator loses control of a subway train, and the fiery crash injures dozens of passengers. Jessie doesn't know it yet, but this crash is inextricably linked to Dylan's disappearance. She has to find out how-and where her son is. Propulsive and page-turning, the latest from bestselling author Rick Mofina is a race-against-the-clock global thriller that will leave you breathless.
