Sandy It's good to read Hillerman's insights into Navajo life in the order in which he presents them.
Moray It would help to read them in chrono order. The girl friend in one book might be long gone and replaced in another book, and you don't know what happened.
Candace Kirchner Not especially. The mysteries stand alone. Some of the personal relationships have history that may be better appreciated in chronological order, but the stories are well enough explained within each separate book.
