Lots of book groups enjoyed and discussed Enger's first novel, Peace like a River, and have been anticipating his next book. I think this new one, too, will be widely read and discussed. (It is projected to be released in paperback this summer.)
The main character Monte Becket, a discouraged author, takes up with a drifter Glendon Hale and adventures with him from Minnesota to California. He gradually discovers that Glendon is running from the law, and much of the plot is their pursuit by an old and determined lawman, Charles Siringo.
The book is part Western, part romance, part adventure story. In fact, as I started reading, the plot seemed to meander too much, and I had trouble figuring out what was motivating the characters to do what they did. But, it all ties together, and the characters discover grace and peace in resolutions that I didn't anticipate.
What set it the book above others, for me, was the lovely language, with charming and fresh figures of speech that show up on almost every page.
Let me quote one of my favorites: "Recently it seemed as if Susannah were looking at the moon while I looked somewhere else--say, at a lake. If I saw the moon in the lake, I believed we were looking at the same place, but let anything disturb the water and we were two people standing alone. We needed to look at something in the same way, as we once had, or as it seemed to me we once had." p. 254
