In the face of danger, the thin line between love and hate is blurred and rules are broken. But are these two prepared to face the consequences? Dr. Kate Wheeler is an independent, feisty emergency-medicine doctor with a perfect life, or at least that's what everyone sees from the outside. Her world is turned upside down when she is forced to allow twenty-four-seven protection, disrupting her independent lifestyle leaving Kate to adjust, or not. She finds herself in unchartered territory as she balances a new love interest at work, never being alone and dodging multiple attempts on her life. If it weren't for her two best friends by her side the stress would be too much, even for her to handle. Her newly assigned security detail, Casey Weston, is harsh, dismissive, and overbearing. His sexy, strong body and bad-boy tattoos are just the exterior to this thoughtful man who has secrets of his own. As he works to keep Kate at arm's length he finds himself equally frustrated and fascinated by this woman who pushes his boundaries. Weston's rules are intense and focused solely on keeping her alive. But as time goes on, will his better judgment falter? Tempers and emotions flare when these two headstrong individuals go head to head, both used to having their own way and unwilling…or too afraid…to give an inch. With Kate's life in the crosshairs and Weston determined to protect her, will their future be happily ever after or torn apart by the same threat that brought them together?
