It's August in Goosebush, Massachusetts, and go-getter retiree Lilly Jayne and her youthful senior pals show no sign of slowing down during the lazy days of summer. But when murder mows over a pesky local, could a Garden Squad member be nurturing a deadly second act?
 
While Lilly digs into a town beautification project, her friend Tamara O'Connor has greater concerns than well-pruned geraniums.

As Tamara becomes the prime murder suspect, Lilly and the Garden Squad ladies set out to prove that someone planted the evidence. With a potpourri of alarming clues scattered around Goosebush, cracking this case means confronting a calculating culprit with a penchant for cutting down anyone who gets in the way . . .
