What to read after The Long Caper: A Time Travel Novel?

In 1963, large animal veterinarian, Paul Canute, driving from Tulsa, Oklahoma to nearby Claremore, encounters a small redheaded man picking weeds on the side of the road. The man introduces himself as Bryan Nappy. Before the end of the hour, Paul and Bryan are pursued, shot at, and almost kidnapped. In desperation, Bryan pulls a pen-sized device from his pocket to summon assistance. But, their escape is not measured in miles, but centuries, and lands them in the year 2110. That "caper" is only the beginning of Paul's travels as he discovers a future he could not imagine, and a chaotic past not adequately reported in history books.
