His pulse is racing

Prince Luciano Bianchi is a top heart surgeon - but as a future king he's expected to rule, not operate! To convince his family that saving lives is where his heart lies, he proposes a temporary convenient marriage to his new colleague, workaholic cardiologist Kelly Phillips. But then their whirlwind 'romance' starts to feel tantalisingly real...

* Vivacious nurse Christy Michaels can easily appreciate a man as handsome as surgeon Linc Maguire. But his gruelling work ethic doesn't impress her! Now Christy's suddenly sharing not only the ER with Dr Serious but parental responsibilities for her best friend's children - Linc's niece and nephew. Can Christy's joie de vivre get the cool, collected doc to cut loose? * As Head of PR for the elite Hollywood Hills Clinic, ex-socialite Freya Rothsberg knows that image is everything. Yet her own facade of calm control is shattered when she meets outrageously sexy heart surgeon Zack Carlton. One wild night later, Freya is shocked to realise that Zack is the clinic's newest recruit! He's an expert with damaged hearts - does she dare trust him with hers?
