Query: Waiting for Anna's return to the West

I really enjoyed Nevada Barr's Ill Wind, Track of the Cat and Firestorm and recommend them highly for mystery readers. I loved the isolated park experience that created these books setting. In "Liberty Falling" the city setting robs me of the things that I want to love about the Anna Pigeon mysteries. The action heated up toward the end of the book, but I had to fight to stay with it. I am waiting for Anna to return to the Southwest or Yosemite or Glacier National Park. This is one of the features that makes me love these books.
