Genealogy Thriller by Elizabeth Lowell
There is a new mystery/romance novel written by Elizabeth Lowell titled "Always Time to Die." Its basis is a professional genealogist, Carly May, who is hired to look into the history of a prominent Southwest family. But someone doesn't want her to find out their secrets and is willing to kill if needs be. It sounds very interesting, so I already have it on hold at my library.
Here is a review by Dan Hays for the Statesman Journal.
