Tony Hillerman - Yet Another Reading Goal!

I'm currently reading one of Tony Hillerman's "Navajo" mystery novels The First Eagle. 

I've read a few of the 18 books in the series, and enjoyed them. But, to be honest, it's been years and just looking at the titles I don't remember specifically which ones I did read.  I'd have to look at the end of each book to tell which of them I did. Still, I think it would be a worthy goal to read them all!

Here's the list:

 
The Blessing Way (1970)
Dance Hall of the Dead (1973)
Listening Woman (1978)
People of Darkness (1980)
The Dark Wind (1982)
The Ghostway (1984)
Skinwalkers (1986)
A Thief of Time (1988)
Talking God (1989)
Coyote Waits (1990)
Sacred Clowns (1993)
The Fallen Man (1996)
The First Eagle (1998)
Hunting Badger (1999)
The Wailing Wind (2002)
The Sinister Pig (2003)
Skeleton Man (2004)
The Shape Shifter (2006)

Pax et bonum
