Sachie’s Hero by Elle James

As a mental health counselor and hypnotherapist, Sachie Moore has witnessed the worst effects of drug addiction, mental and physical abuse on young people. After working with victims of violent crimes for the Honolulu Police Department, she finds herself the target of a stalker. To get away from the soul-sucking stress of her job and leave her stalker behind, she moved to the Big Island of Hawaii. There, she sets up her own practice, helping teens deal with addiction and abuse but on a much smaller scale.
Once again targeted by a mysterious stranger, Sachie calls the Brotherhood Protectors.
Tagged as the strong silent one, Teller Osgood might not joke around with the others, but he’s fully committed to the team and would sacrifice his life for any of the men he calls brothers. Assigned to protect a pretty mental health counselor, he must face the demons of his childhood to expose the source of Sachie’s threats. In a race against time, Teller and Sachie risk their lives and hearts to stop evil before he claims his next victim.
