When her elderly mother suffers a stroke, Ivy Lutz leaves her life as a Buddhist nun in Sri Lanka and returns home to northern California. Her sheltered life is blasted apart by a series of murders, which she attempts to solve with the help of a smitten detective. She understands why someone might want to kill her stepfather, who it turns out is a smuggler on the run, but what about her mother? Was she was murdered, too? As Ivy struggles to live by her Buddhist principles and employ her mindfulness skills, she discovers they both hinder and help in her search for the truth.
