I'm pretty sure her books are Urban Fantasy, but there's no category for it in here so, I'm putting it in the paranormal slot. I cannot tell you how much I love these books though.
This series is wonderful. Ms Murphy blends Native American legends with the modern world so well that you expect to walk outside and see the magice happening your own front yard. Gary, is one of the most interesting characters I've ever read, he's supporting cast, a buddy, but still, she paints him as the most vital and hey, sexy 73 year old ever. Think a cross between Sean Connery and John Wayne with a whole lot of crusty humor. I love her protaganist female lead too. Joanne is stubborn, goofy, vulnerable, and most importantly, human.
Oh, but most important of all is.. I got the new book.
But if you haven't talken as stroll in the Walker Papers yet, here they are in order with the ISBN#'s included
There's also a Walker Paper Short Story in this book
