A “haunting meditation on trust, hope and love” by a woman who adopts and trains a Golden Retriever puppy to become a search-and-rescue dog (People). In the wake of the Oklahoma City bombing, Susannah Charleson’s attention was caught by a newspaper photograph of a canine handler, his exhausted face buried in the fur of his search-and-rescue dog. Susannah, a dog lover and pilot with search experience herself, was so moved by the image that she decided to volunteer with a local canine team, plunging herself into an astonishing new world. While the team worked long hours for nonexistent pay and often heart-wrenching results, Charleson discovered the joy of working in partnership with a canine friend and the satisfaction of using their combined skills to help her fellow human beings. Once she qualified to train a dog of her own, Charleson adopted Puzzle—a smart, spirited Golden Retriever puppy who exhibited unique aptitudes as a working dog, but was a bit less interested in the role of compliant house pet. Scent of the Missing is the story of Charleson’s adventures with Puzzle as they search for a lost teen; an Alzheimer’s patient wandering in the cold; and signs of the crew amid the debris of the space shuttle Columbia disaster—all while unraveling the mystery of the bond between humans and dogs. “A riveting view of both the human animal bond and the training of search and rescue dogs. All dog lovers and people interested in training service dogs should read this book.” —Temple Grandin, author of Animals Make Us Human

From New York Times bestselling author Jennifer A. Nielsen comes a thrilling World War II story of espionage and intrigue, as one girl races to crack a coded message to save her father and the French resistance. Six hundred and fifty-seven days ago, Meg Kenyon's father left their home in France to fight for the Allies in World War II, and that was the last time Meg saw him. Recently, she heard he was being held prisoner by the Nazis, a terrible sentence from which Meg fears he'll never return. All she has left of him are the codes he placed in a jar for her to decipher, an affectionate game the two of them shared. But the codes are running low, and soon there'll be nothing left of Papa for Meg to hold on to at all. Suddenly, an impossible chance to save her father falls into Meg's lap. After following a trail of blood in the snow, Meggie finds an injured British spy hiding in her grandmother's barn. Captain Stewart tells her that a family of German refugees must be guided across Nazi-occupied France to neutral Spain, whereupon one of them has promised to free Meg's father. Captain Stewart was meant to take that family on their journey, but too injured to complete the task himself, he offers it to Meg, along with a final code from Papa to help complete the mission -- perhaps the most important, and most difficult, riddle she's received yet. As the Nazis flood Meg's village in fierce pursuit, she accepts the duty and begins the trek across France. Leading strangers through treacherous territory, Meg faces danger and uncertainty at every turn, all the while struggling to crack her father's code. The message, as she unravels it, reveals secrets costly enough to risk the mission and even her own life. Can Meg solve the puzzle, rescue the family, and save her father?
