Dr. Bethany Winstead lives by the rules: save lives, excel, and never, ever mix work with pleasure. Especially not with Dr. Luca Michaelson, the devastatingly charming surgeon whose conquests are legendary and whose disregard for attachment rivals his skill in the operating room. He's a complication her meticulously planned life can't afford.

Luca thrives on the adrenaline of the ER and the chase outside of it. One-night stands are his specialty; emotional entanglement is malpractice. Yet, the intense focus and unexpected fire in Dr. Winstead's eyes during a high-pressure case flips a switch he didn't know existed.

She sees a walking hazard sign in designer scrubs. He sees the one woman immune to his charm – and finds himself utterly intrigued. In the demanding world of surgery where one wrong move is critical, will giving in to this magnetic pull be the biggest risk of their careers... and their hearts?
