One summer morning, a flight takes off from New York to Los Angeles: there are 192 people aboard. When the plane suddenly crashes, twelve-year-old Edward Adler is the sole survivor. In the aftermath, Edward struggles to make sense of his grief, sudden fame and find his place in a world without his family. But then Edward and his neighbour Shay make a startling discovery; hidden in his uncle's garage are letters from the relatives of other passengers—all addressed him. Following the passengers' final hours and Edward's unique coming-of-age, Dear Edward asks one of life's most profound questions: What does it mean not just to survive, but to truly live?
