From the official Nevada Barr blog:

Nevada’s 17th Anna Pigeon mystery, set in the Glen Canyon National Recreational Area is complete and submitted to the publisher. It’s due out some time this year — sorry we don’t know the title or release date yet.

For those who don’t know, Anna Pigeon is a law enforcement National Park Ranger. Her work takes her to various parks around the country where she inevitably finds criminal activity of some sort going on. I’ve written a couple of blog posts about her and the author who created her.

The books are thrillers rather than mysteries, and they’re excellent.
