The Left-Hand Path — Jeff Erno

William Austin has always wanted to be a nurse, though he's no longer sure the gratification is worth the pain of losing a patient. For now, he's a nursing student and works two jobs -- barista and private nurse. Will meets Blaine Coventry at the coffee shop, and when the altruistic young attorney offers him a job caring for his Uncle Elliot, Will accepts. Will finds that Elliot's stroke has left him unable to walk or talk, and Elliot's husband, James, says the goal is to keep Elliot comfortable until he passes. But Will starts rehabilitation, and his patient soon begins to make progress. When James resists, Will realizes something isn't right, and investigates. Then he discovers a chilling secret that threatens to forever change Will's life... or perhaps end it.
