Fate hasn't exactly been kind to twenty-year-old Alexandra. Unless you count the fact that she can communicate with animals, the only piece of luck she's ever had was being rescued by a werewolf and landing in a forever home with an eccentric couple and their unusual pack of animals. It's taken twelve years to earn the official title of Shepherd but she's now mostly trained, fairly effective, and the first female in over two centuries to hold the position as protector of animals. All animals... The Territorial Council isn't thrilled with her new title of Shepherd, but they don't have any more control over the appointment than they have over her. All they can really do is wait for her to screw something up - which Alex is determined not to do. Everything changes when a chance encounter with a genetically modified Shifter leaves Alex shaken and initiates a quest to locate its maker. In a desperate bid to save her pack, Alex must infiltrate the Parallax Corporation - an international organization with their hands in everything from biomedical engineering to publishing. They have now expanded their efforts to include terrorism and are attempting to breed the perfect weapon. Despite years of training and enough money from her live-in pack of misfits to finance a small country, Alex finds herself woefully unprepared to tackle the new threat. To make matters worse, Alex must work with a mysterious man who's been trying to kill her since the day they met. Together with her pack, Alex must learn how to stop the biological cloning and find those responsible for the plan before it really does become a global threat.
