The Preacher and MacCallister series is a crossover that brings together two established Johnstone character lines. Preacher, the mountain man who raised Smoke Jensen, is one of the oldest characters in the Johnstone universe. The MacCallisters are a well-known frontier family with their own series. Putting them together gives readers a team-up that draws on decades of Johnstone storytelling.
The series ran four books from 2019 to 2022, beginning with Frontier America. They Came to Kill and When All Hell Broke Loose followed, with each book throwing the combined cast into large-scale frontier conflicts. The crossover format works because both character groups bring different strengths. Preacher is the grizzled wilderness survivor; the MacCallisters bring family loyalty and frontier grit. For readers who have followed either series on its own, seeing these characters work together adds an extra layer of enjoyment.
