What happens when nature calls - and someone falls - prey to a vicious killer? Naturalist Kristen Matthews is heading up a team of volunteers working to eradicate pesky weeds during a workday at the Nature Station. When one of the volunteers wanders away from the rest of the group and ends up eradicated himself, Kristen is concerned for her safety, as well as the Nature Station's reputation. She starts digging and unearths some interesting dirt on her squeaky clean helpers. Is it possible one of them despised the victim enough to kill him? Follow Kristen's lead, as she wades through the wildflowers tracking the murderer, and learn a little about nature along the way.
