Desperate for a solution to their endless struggles with weight loss, the supper club members decide to sign on with Wellness Village, a new-age health center promising life-changing improvements through hypnotherapy. It's a mesmerizing experience, to say the least, but when the village's fresh food festival is disrupted by an angry mob of protesters and a local councilman is found dead, librarian James Henry and his friends trade in their newfound sense of calm for a tense hunt for a cold-blooded killer.

Sorting through a list of suspects that includes an herbalist, an acupuncturist, and various other holistic healers who are all cool as cucumbers, the supper club members begin to suspect that all is not well at Wellness Village. But before their efforts can bear fruit, the body of another murder victim is discovered, and James and his friends realize they'll have to sink their teeth into the investigation to help root out a rotten apple.
