Moonrise Over Malhutan

The first of a series of four Sci Fi murder mysteries takes place in the futuristic cooperative society of Malhutan, following the free prequel "The Malhutan Proxy" (which should be read first). Devon is sent to Malhutan when a mother finds the head of her son along with roses and a Mothers Day card on her front porch. Can he find out why the student was murdered, before the killer strikes again?
