After the Unified World Pact of 2045, people lived in a state of peace and prosperity previously unknown in human history. The World Guild, a new global government, managed all the needs of humanity and the animals it loved. Then in 2086, a security breach of Xavier Labs in Colorado and Zheng Industries in China released the deadly experimental agent XSKL435. Anyone outside was dead within minutes. As statistics on the death toll are gathered from all over the world, Abby, the six-week old dog-daughter of Bill and Teresa Maxwell, was one of only four known surviving canines. News services soon announce that the other three dogs had succumbed to the deadly poison. Abby was now the last dog. You’re invited on a journey with a puppy who longs for home after she is confiscated and held captive at a lab, and the family who are determined to get her back at all costs. After escaping from the lab, Abby must quickly learn how to survive in the wild. Bill and Teresa must devise a plan to find Abby without being arrested themselves. Neither Abby, or her parents know whether their plans will work, if they will survive the journey, or if they will be reunited. But love of family drives them onward.
