Rye Mallett, a fearless “freight dog” pilot charged with flying cargo to far-flung locations, is often rough-spoken and all business, but soft on regulations when they get in the way of meeting a deadline. But he does have a rock-solid reputation: he will fly in the foulest weather, day or night, and deliver the goods safely to their destination. So when Rye is asked to fly into a completely fogbound northern Georgia town and deliver a mysterious black box to a Dr. Lambert, he doesn’t ask questions.
The year is 1934. With the country in the stranglehold of drought and economic depression, Ella Barron runs her Texas boardinghouse with an efficiency that ensures her life will be kept in balance. Between cooking and cleaning for her residents, she cares for her ten-year-old son, Solly, a sweet but challenging child whose misunderstood behavior finds Ella on the receiving end of pity, derision, and suspicion. When David Rainwater arrives at the house looking for lodging, Ella senses that admitting Mr. Rainwater will bring about unsettling changes. However, times are hard, and in order to make ends meet, Ella’s house must remain one hundred percent occupied. So Mr. Rainwater moves into her house…and impacts her life in ways Ella could never have foreseen.
