Bad Company by Lisa J. Hobman

Scottish psychologist Doctor Kelly Ann Darrow loves her career and has never permitted her feelings to impact her professionalism, but when biker Cameron Iss arrives in her care, she finds herself inexplicably drawn to the unconscious man. His tattoos and the mysterious circumstances of his arrival intrigue her to distraction. Cameron Iss awakes in a strange country with no memory of how he got there and no knowledge of who he is. He takes out his frustrations at his amnesia on the sexy doctor enlisted with helping him unlock his mind. A mutual chemistry forms between them, and Kelly is plagued with guilt at her unethical and inappropriate attraction to this, her most perplexing patient yet. As his memories begin to return and they discover more about his violent past and his connection with a motorcycle club in America, the element of danger both excites and frightens Kelly, and nothing can douse the erotic fire he has sparked inside her. Will Kelly risk her career, her reputation, and all she is for the man who has ignited a dormant passion within her or will his returning memories steal him away for good?
