Wow. This is really different and I love it. Action alternates between present day archeologists unearthing an unusual find and the Anasazi going through an unusual crime spree of scary proportions. It certainly kept my attention and made me think.
I have now just barely started The Demon Crown by James Rollins. It begins with a trip by Alexander Graham Bell to Italy to retrieve the bones (now under threat of excavation by a mining company) of the original gifter of the money used to build the Smithsonian Institute. And, of course, undercovers a dangerous mystery while so doing.
