The Last Song Dogs (Trade Ellis Mysteries)

Trade Ellis is a dirty-shirt cowgirl--part Apache, part rancher, and all private eye. Unfortunately, there's not much call for investigators on horseback. But as her 25th high school reunion approaches, someone starts thinning the ranks of the old cheerleading squad. Trade has enough suspects to fill a yearbook: the fading beauty, the rich girl, the loser, the nerd. Because someone wants her to join the cheerleading squad--in the morgue.
