It certainly won't be the first one. I've written four cowboy/rancher books, more if you include a cowgirl novel and those that were simply set in ranch country. I've done a lot of research, spent a lot of time in Montana and Wyoming, and...there's just something about a cowboy hero. I think it's the attachment to the land. And the horses. And maybe the music. The loner lifestyle. The boots. The ruggedness. Or more likely, all of that.
Whatever it is, I'm thinking cowboys.
But don't be surprised if I end up writing about ballerinas and Wall Street tycoons. Writing seldom follows linear paths. It's one of the things I find most frustrating about being a writer and also one of the things I love best about it. (Besides, in what other line of work could I spend my days thinking up stories and writing books about cowboys? I know just how lucky I am).
