A science fair project vandalized, a warehouse explosion and two dead bodies.
When Holly Donnelly gets invited to speak about home -composting at Pineland Park Community College’s Eco-Fair, the last thing she and her sister Ivy expect is to become involved in, not one, but two murder investigations.
Throw in a controversy over a student GMO experiment that yields unexpected results, and once again the gardening duo find themselves called upon to help those falsely accused. Are the murders and the experiment connected? Can the stalwart sisters find the real killer and save the students’ scholarships? Not without a little help from their friends. Joining them to solve the mystery are trusted allies from past adventures, Kate Farmer and her neighbors, Benny and Razor, along with the plucky Peppy Alvarez and rookie FBI agent Nicky Manelli.
