I have really enjoyed reading the last few books - especially Dan Brown's Inferno (the latest Robert Langdon mystery/thriller) and Margaret Coel's Buffalo Bill's Dead Now, a Wind River Reservation mystery. Both books took intensive research and both of them grabbed me and wouldn't let me stop reading until I finished each book. There were unexpected twists and turns in each story, and I highly recommend both of them. As usual, Inferno has the characters running about in Europe, seeking clues and answers. The majority of Margaret Coel's book takes place in and around the Wind River Rez in Wyoming, with some glimpses back in time (1890) seeing The Wild West Show in Europe. They are super books.
Here are a few places mentioned in each book:
