The series is about a young man named Carter, who navigates through a range of criminal activities while on his deliveries. The first book opened as Carter was attempting to make a delivery in Indiana when he stumbled upon an ongoing home invasion and was confronted by a large-scale villain who threatened him with a gun. Despite these challenges, Carter manages to overcome them, often times without being seen as a threat. The series also includes an underlying mystery that connects with Carter's father, who was murdered on the job. The next book will resolve this mystery.
