The Fallen Man is the 12th in the Joe Leaphorn/Jim Chee series by Tony Hillerman. This is a great series, although I’m perhaps a little biased because my dad’s family is from the region. Still, some of the series books have won/been nominated for lots of awards, and this one has a 4.8 out of 5.0 rating at Amazon US. It has dropped to $1.99 at Kindle and Kobo US. Hillerman’s books (other than the first few) don’t go on sale very often, so grab it if you want it.
