Promise has a final chance to save her baby brother from the vampire disease. But can Peter, a half and half, her friends Mark and Lea and even the National Guard help her with the impossible? This is the last book in the Blood Run Trilogy. It is 1985 and the United States is reeling from a disease that has taken huge, bloody bites out of the country as people are changed into vampires. The survivors have grouped together in remote outposts and the National Guard is the lifeline that runs between the outposts, bringing news and supplies. In Wereburg, New York, a young woman named Destiny Riser has lost her parents in the plague but saved her little brother, Chance. But the outpost she brings him to is still young and learning and in an accident of fate, it is ravaged by vampires. Destiny sees her brother bit and changed and from that moment on, rechristens herself ‘Promise’ and vows to release Chance from his nightmare, nighttime existence.
