He has the hands of a healer. And the instincts of a killer. Dr. Marcus King is a walking contradiction. Born in the slums but working in the ER, he is drowning in debt and hiding a secret: a mastery of ancient, mystical Eastern medicine. All he wants is to pay his bills. But when a disastrous blind date throws him into the middle of a violent bank heist, Marcus is forced to act. Armed only with his silver acupuncture needles, he saves a billionaire heiress and captures the attention of Liberty City’s dark underbelly. Now, a hero by accident, Marcus is hunted by design. Caught between a corrupt hospital board and a cartel peddling "Blue Ice"—a terrifying new bio-drug—Marcus must team up with Detective Scarlett to expose the truth. But as the city falls into chaos, the good doctor learns that to cure the disease rotting Liberty City, he might have to break his oath to do no harm.
