The Lost Boys by Faye Kellerman

 Retired LA detective Peter Decker and his wife Rina have left California for a quieter life in small-town New York State. Peter and his partner Tyler are assigned a case involving a developmentally disabled man who vanished during a field trip with people from the facility where he lived. While searching for him, the cops find buried bones that turn out to be from a college student (one of 3) who disappeared on a camping trip 10 years earlier. So Peter and Tyler find themselves working on a very cold case along with their missing persons case. By the end, they come to a better resolution of the cold case. And Rina and Peter are getting ready to head off to another new adventure in Israel.

I read somewhere that The Hunt (which follows this book) is the last in the Peter and Rina series but that it was very violent and spent more time on peripheral characters than on Peter, Rina, and Tyler. So I think I'll skip it and end with this one while I still have a favorable opinion of this series.

One wonders why authors of popular series decide to end their long-running series on such a bad (and for readers, disappointing) note. Stephen White did something similar with his long-running Alan Gregory series, in which the last book torched pretty much every relationship in his books. Is this so readers don't miss the books?
