Western readers have discovered a new favorite in Michael Zimmer.  In response, the library recently added two back catalog titles.  In “Leaving Yuma”, a sheriff frees a man from the Yuma pen. The hitch? He has to guide the sheriff through the Sonora Desert to make a prisoner exchange with some seriously dangerous banditos.  “Miami Gundown”, meanwhile, recounts a dangerous cattle drive. Yes, in Florida.  Also getting good reader comments is John D. Nesbitt  (Across the Cheyenne River; Trouble in Redstone).
