Isobel Donnelly has a perfect life. Married to a renowned orthopedic surgeon who's employed at the illustrious Sydney Harbour Hospital, she also has a successful and satisfying career as a pediatric nurse. Life couldn't get any better. But then her babies arrive and the husband she adores turns into a cold and angry stranger. Her perfect world is shattered the first night he hits her. Now, she's trapped in a violent marriage with nowhere to turn. Her husband has threatened to kill her and the kids if she ever dares to leave. In public, they're the perfect couple, but inside, she's slowly dying... Mason Alexander has relocated to the city to take up his dream job as a pediatric doctor at the prestigious Sydney Harbour Hospital. Recovering from a failed marriage, he's determined to put the change of scene to good use. The distractions and demands of his new job are just what he needs to get his life back on track. Then he runs into Isobel Donnelly and his world is once again turned upside down. He's loved her since they were children. She's the reason his marriage failed. But Isobel's still married to his nemesis: the incomparable Nigel Donnelly. From all accounts, the two of them are still blissfully in love. Vowing to steer clear of the woman who's haunted his dreams for far too many years, Mason does his best to avoid her, but Isobel continues to seek him out and he can't help but notice her assurances about her happy marriage appear a little forced. When she arrives at work with a blackened eye, he's immediately suspicious: There's no way she fell over toys left in the way. The thought that Nigel might be abusing her is abhorrent, but the signs are there for all to see. Will Mason be able to convince her to leave her husband...or will they both die trying?
