I've read other Gideon Oliver mysteries and some of them are pretty good.  Neither the anthropology nor the relationship values in this one age well.  The Ishi/Yahi theme is tenuous at best, and the anthropological approach is downright cringe.  I'm all for a nice cozy romance between people who aren't hormonal 20 year olds but the way Gideon (who is clearly incompetent in the rain forest) tries to lay down the law with Julie is just... no.  Some of the other books are good but unless you are a devoted completionist skip this one.  So much ugh.   The mystery is barely there, it's mostly romance and terrible, terrible investigations that don't deserve the word ethnography.
