Eleanor met Aaron when she was just a teenager and he was working at a local record store--older, cool, experienced, and with an electric personality. Escaping the clichés of fleeting young love, their summer romance bloomed into a relationship that survived college and culminated in a marriage and two children... On top of the typical stresses of parenting, money, and work, there were Aaron's untended wounds of depression, addiction, and family trauma. Then, when burning lesions appeared on his body overnight, Eleanor was as baffled as his doctors. There seemed to be no obvious diagnosis, let alone a cure. And when the lesions gave way to Aaron's increasingly disturbed concerns about parasites living inside him, the husband she loved began to unravel before her eyes.
