if you're looking for something similar, you might enjoy Craig Johnson's 'Walt Longmire' series. Both authors excel at creating rugged, atmospheric settings with a strong sense of place—Wyoming for Box and Absaroka County for Johnson. The protagonists, Joe Pickett and Walt Longmire, share a down-to-earth, lawman vibe, though Longmire has a bit more of a world-weary, philosophical edge. The mysteries are tightly plotted, and the supporting casts are richly drawn. Another author to check out is Nevada Barr, especially her 'Anna Pigeon' series, which features a park ranger solving crimes in national parks. The outdoor settings and procedural elements are reminiscent of Box's work.
For a grittier take, Paul Doiron's 'Mike Bowditch' series follows a Maine game warden dealing with crimes in the wilderness. The blend of natural beauty and human darkness is similar to what Box does so well. If you like the family dynamics in 'Joe Pickett,' try William Kent Krueger's 'Cork O'Connor' series, which mixes crime with Ojibwe culture and family struggles. These authors all capture the spirit of Box's work while bringing their own unique flavors to the table.
